Well the first post says the instructions no longer work... in any case
I tried adding
http://triodeapplets.googlecode.com/svn/trunk/usbtestrepo.xml as an

It works OK - it is a Touch Appley so it will only appear in the Touch

Where can I find the Kernel Updater? I have EDO installed but can't find
Kernel Updater anywhere in the menus. I'm trying to get USB 2.0 working
with a Mytek DAC and read that I should try a different kernel.

Hi,

regardless of whether it could be improved on the EDO side
(I was able to play in asynchronous mode using build in aplay player)
it works now with new firmware for VIA VT1731.

If you have any dac using VIA VT1731 (or Audio-gd with usb-32) there is
new firmware
that allows to play in asynchronous mode using EDO plugin.


Link to firmware and instruction you can find here:
http://www.head-fi.org/t/500369/audio-gd-digital-interface/3870#post_9563929

I've flashed firmware on dac and squeezebox works now in asynchronous
mode.


The last thing that I want to do is to upsample on squeezebox side.
Anyone knows how to set up fixed resampling to for example 176,4kHz?

Hi Triode,

I use a 1794 based DAC with a WaveIO 2.0 USB module from Lucian Luckit.
It worked fine for 4 weeks, but now (when I power off the DAC) the Touch
doesn't recognize the DAC anymore. To get it working again I have to
reboot selecting the spdif Out and choose the Luckit 2.0 USB output
after that. OR I reload/reboot your kernel and it plays instantly. I am
running the 0.8 kernel and the 7.7.2 LMS. I have tried version 7.8, but
that doesn't help.

Do you have any idea? 

Peter

Hi Triode,

There was no go for me to test this in different way than installing
Linux
on my notebook. So I will describe my steps to get Linux because this
can be good test case to setup environment for such tests.

I didn't want to make any changes to SSD drive in my notebook so after
reading some pages I found that we can install Linux on USB.
After few more queries to google I found such software: 
www.pendrivelinux.com/yumi-multiboot-usb-creator/

Wonderful thing. Because of this next steps will be easy. After
inserting
USB stick (you don't have to worry about data on it if you have fat32 on
it, tested)
and running this yumi I've selected 'slacko puppy' distribution. I've
found that
this distribution is small and is modern too. Using iso check box you
will be
redirected to proper iso file download. You have to save iso file and
after
download select it in yumi. After clicking 'create' you have bootable
usb
stick with Linux. Pretty simple.

After booting this puppy if you are clicking on flac file it's
automatically run
Pmusic program and starts to play. Because sound went from my notebook
speakers I've set my USB DAC clicking start menu - setup - ALSA sound
wizard
- Three: multiple sound cards. Change works without reboot.

To have the same test environment I would use following example to play
music:
mplayer http://radio.cesnet.cz:8000/cro-d-dur.flac -ao alsa

And music is played correctly.

Output from lsusb command in attachment.

I don't know how to switch re-sampling. Because playing 96khz file gave
me 48khz.
Checked in stream0 and hw_params. So I edited
/usr/share/alsa/alsa.config
and putted a following change:
defaults.pcm.dmix.rate 192000

Momentary freq in most of the time is 192000 and change to 192031 about
3 times
per second.

I've tried 44100 too. And sound was OK too. Momentary freq 44078 and
44110.

cat /proc/asound/version returns 1.0.24
kernel version is 3.1.10

 I'm not familiar with linux but to get new ALSA you have to get

Can you prove that it works in ASYNC mode on a modern linux desktop -

Hi Triode,

I've upgraded usb chip to firmware #4. But have following problem.
When playing 44.1kHz music /proc/asound/Audiogd/stream0 returns:

Playback:
Status: Running
Interface = 1
Altset = 3
URBs = 3 [ 7 8 8 ]
Packet Size = 776
Momentary freq = 48000 Hz (0x6.)
Feedback Format = 14.18

and used interface is following:

Interface 1
Altset 3
Format: S32_LE
Channels: 2
Endpoint: 4 OUT (ASYNC)
Rates: 44100, 88200, 48000, 96000, 176400, 192000
Data packet interval: 500 us
Max Packet Size = 776
EP Attribute = 0x0


And sound isn't OK. You can hear something but sound is constantly
interrupted.
I can change this interruption interval by changing buffer size. But I
can't find
setting that the sound is OK.

It seems that problem is 14.18 feedback format. That is not standard
16.16.
But reading about ALSA it seems that they tried now to detect when to
send data
to DAC using packet sizes or something like this.

I don't have other computer with Linux. But I would like to check the
newest
version of ALSA. EDO using version 1.0.16. The newest seems to be
1.0.26.
Is there a chance to get EDO with the newest ALSA version?

Or maybe you know what to do in such not standard feedback format?

Is this a Tenor device - try firmware #11 for that.  Otherwise I'm not
currently planning and updated kernels for Touch as its too hard to
merge additional changes given no support from Logitech for newer
kernels - hence the need to keep to the old version of alsa.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...

2012-12-15 Thread Eryk

First of all, thanks Triode for this great applet.

I'm new owner of Audio-gd NFB-1.32 DAC.

Because this DAC sounds better when connected by USB
I tried your applet. Installation was very easy. So far
I only played 16/44 files and have not noticed any problems.

But checking information about USB device in settings (that is
provided by EDO applet) I got information that is operating in
adaptive mode.

As I understand in this mode SBT is master (and his clock)
when sending digital audio to DAC. My DAC is with the upgrade
for USB clock (additional TCXO clock). So going to asynchronous
mode and using this TCXO clock should be a better solution for
sound quality.

Audio-gd advertise this DAC as asynchronous so it seems that
USB chip VIA Vinyl Audio VT1731 should be compatible with the
asynchronous mode. 
http://www.via.com.tw/en/products/audio/usb/vt1731/index.jsp

So after reading posts from this topic I tried to get more info
from SBT. I used WinSCP (I'm a Windows user) to connect to SBT.
For anyone who would like to use this software there is some hint.
Often, I received an error message connected with ssh and groups.
Here is the solution:

go to folder
/usr/bin
press Shift+F4 for creating new file, name it
groups
in editor past following code
#!/bin/sh
echo root
save, close editor, when folder will be updated with
new file, go to the properties under right click mouse menu
on this groups file and put
0755
as access rights or you can invoke console Ctrl+T and
put following command
chmod 0755 groups


So I was able now to invoke dmesg on SBT.
Here is the result: http://pastebin.com/fSbppG0g
(you should be able to find it in the attachment too)

Here is the content for /proc/asound/card1/stream0

/proc/asound/card1$ cat stream0

For WinSCP users - because this is file generated by
system so don't see content by opening this file.
Under console you have to invoke command
cat /proc/asound/card1/stream0


Now is the question. How to enable async mode?
What I have to change in files under SBT? Maybe
I can invoke some command to enable this mode?
Or install additional packages?

If you have any ideas, please send them to me and
I will try them.

Thank you for any help.

Hello there,

here is a genius at work. Thank you for your efforts, triode.

I´ve recently acquired a Teac UD-H01 dac, but unfortunately I got no
SBT, so I cannot test your kernels numbered 9-12.

I have massive problems with playing back audiofiles beyond 48kHz. The
playback of high-res audio files clicks/crackles/pops. 

I´ve tried it with 2 newer Ubuntu kernels (for x86 based machines):
3.2.23 and 3.5.0, same behaviour as mentioned above while playing back
files with aplay.

You´ve stated that your  Tenor kernels were designed to work around
the frequency corruption seen with the Tenor chip. Is this frequency
corruption the reason for the the crackling playback or are there maybe
any other factors that could disturb the USB audio stream?

Well if its the same tenor chip as we were testing, it corrupts the
feedback messages so if you look at the momentary frequency in
/proc/asound/card/stream0 then it will probably look wrong?

The teac UD-H01 has the Tenor TE8802 chipset.

Have a look here

http://pastebin.com/hiqpra58

the frquency is jumping in between 183994 Hz and 14 Hz while playing
back a 192kHz file. So I assume this is the frequency corruption you are
talking about.

Could your patch be applied to other kernels which are not for ARM based
machines like the SBT?

Yes this looks similar.  I did email Tenor, but they did not appear keen

Excellent, thank you for beeing so kind to provide us with the code. I
will email Tenor and Teac also. They claim it to be an USB Audio Class 2
device, but obviously they disregarded UAC2 conventions while designing
the chip respectively writing the firmware code for it.

I´ll try to build a new kernel with your provided code. I´ll feed you
back then.

Do you think the bug/flaw is in hardware design or in the firmware code
of the TE8802 chip?

Thanks again...

This is basically ensuring the interval requested for the syncpipe (the
feedback connection) is not too long for the size of the ehci schedule
maintained by the linux kernel - essentially it can't schedule periodic
intervals which are too long as the size of the schedule held in memory
means that scheduling packets into the future goes beyond the size of
the schedule held.

Logitech should be ashamed with their new product roadmap, there's

They obviously saw it as a quick way into the AV streaming sector but
then screwed up because they didn't understand the AV market either!

Just to confirm my initial impression. EDO 0.6 (option 999) + TT3.0 +
SBGK's blog settings delivers much improved sound. Not only wonderfully
balanced, but also with greater nuance in both vocals and instruments.
More layered soundstage as well. Am listening to Janos Starker playing
Bach cello suites, and have to say his cello never sounded as real as
this before in my system. 

for me the best sound is via spdif using the above settings, the sound
using EDO/USB is more hifi sounding ie detailed, but less musical

So from what I gather, even if I'm not using USB, I need to uninstall

I'm getting good sound after installing EDO but when I tried turning off
the Touch's screen through Putty it couldn't find TT. Also I tried a

Being unable to play 24/192 doesn't really bother me as I only have one
file but I would like to be able to kill the screen and daemons again. 

Is it possible that EDO flushed TT3.0? 

Also - I was under the impression that EDO in stock form was a bit thin

Running slow at 192k is probably because you are playing back as wav/pcm
which needs the 7.8 version lms and the player firmware.

For 7.8 you need to install the beta version of LMS first - search this

For the display off app, you go into settings, screen, screensaver and
change the when playing saver to display off.

Kernel #12 is intended for tenor 8802l devices.  It tries to correct
slightly more cases than kernel #11 for corrupted feedback packets which
the tenor device seems to produce.  If you have a tenor 8802l based
device I would be interested in feedback on kernel #12.

 It appears that the Tenor device corrupts the feedback messages it sends
 to the linux host.  This firmware contains some code to work around the
 specific corruption seen on diego's device.  This may work for other
 users, but its possible that we need to make the workaround more generic
 to work for other instances of the Tenor device.

Anyway it is a good start. I think this will put pressure on the
firmware developers at Tenor, and this is fine. They now know that it is
known that their firmware (or even hardware?) has flaws. So let's hope
that this will motivate them to bring out a stable set of firmware and
drivers. Manufacturers will obviously think twice, if they prefer the
Tenor chip or another one, that may be more expensive or less advanced
in some aspects, but more robust and therefore causing less problems to
clients. As seen on the audio-gd website right now, they are calling for
reports about issues... so it seems, that they have been under pressure
to start selling their chip in a rather beta stage...

Hi there fellows.

Good news for owners of a DAC using a TE8802L - USB-connection! It can
now be connected over Asynchronous USB.

It works for audio-gd DACs. It might work for other TE8802L - Based
DACs, too. In particular for instance, TEAC UD-H01.

PLEASE REPORT HERE, IF YOU GET YOUR DAC TO WORK, OR NOT.

And please say thank you to Triode. He worked on that many hours. I
suppose he is British, and he was working even during the GB against
Italy - game yesterday evening! Only the numerous tryouts and log file
creations, that I did to assist Triode, took me hours, so developping
must have been a huge task!

Disclaimer: This current version is still in Development Stage. However,
I am able to play up to 24 bit / 192 khz - files with it. And it sounds
great. But nobody can guarantee, that this will work for all users and
any setups! All the modifications in this guide are at your own risk.
They are not supported by any vendor, nor by myslef, nor by the
developper Triode, nor by anybody else. They are in particular not
supported by Logitech, audio-gd or Tenor (gfec). Any damage will be on
your own risk! If you go further in this guide, you accept this
condition!

However... For me, I can tell you, that it works. I have a Squeezebox
Touch connected over USB to a audio-gd DI.

Here is the guide:

- I recommend, you use a DAC, that is externally powered, NOT
USB-powered. The DAC may work over USB power, but I can not tell for
sure. If your DAC has no separate power input, this usb - linear power -
interface may help, and it will by the way enhance your sound quality:
http://www.aqvox.de/usb-power_en.html ).
- Everything on the SBT and on the Logitech Media Server is updated to
the latest versions and runs with default settings. 
- Logitech Media Server must run on an external computer (or NAT), and
Squeezebox Touch must be connected with this external server via
Network. LAN is best, if possible.


Now:
- connect the TE8802 - based - DAC to the Squeezebox Touch (SBT) over a
good USB cable.
- Access the configuration screen of the Logitech Media Server over a
web browser, go to the plugins - tab and add
http://triodeapplets.googlecode.com/svn/trunk/usbtestrepo.xml as
additional repository. Choose to show third party plugins.
- Go to the SBT, go to the applet installer (in settings, extended
settings)
- Uncheck the tab that limits the choice to recommended apps
- Choose Enhanced Digital Output and install it. SBT will reboot,
download a Kernel and reboot again.
- Play a song, it will not sound, but this is to make sure, your SBT is
connected to the server
- Go again to the applet instller and install Kernel Updater. SBT will
reboot.
- Go to Kernel Updater (in settings, extended settings). Install Kernel
#11. Wait until SBT reboots completely.
- Disconnect the power connection of the SBT and disconnect power from
the DAC. Wait 10 seconds.
- Power on DAC and wait 10 seconds
- Power on the SBT and wait until it boots
- Go to the Audio-Settings and choose Digital Output. Choose your DAC
over USB!
- Listen to the music

Recommendations: Choose Screen disabled screensaver while playing.
Additional mods to the SBT, like TT3.0, will probably NOT work. Maybe
they can work, but you will have to manually adjust priority settings
and buffer settings, etc. You find lots of discussions about that on the
audiophile threads. However, these settings may make the SBT not to
respond anymore. This can usually be resolved with a factory reset, but
again, there is no guarantee. IMPORTANT: Please, discuss audio quality
and audiophile mods only in the audiophile threads (
http://forums.slimdevices.com/showthread.php?94855-Triode-s-USB-24-192-plug-in-sound-quality-impressions
). Do NOT discuss audio quality here! THANKS! 

To revert everything back to the original stage and factory defaults:
- Power on the SBT
- Hold down the little reset button on the back of the SBT just above
the DC power plug for 10 seconds. This does the factory reset of the
settings, but NOT of the installed Kernel !
- Let the SBT boot up to Factory Settings.
- Go to the Software Updating Menu (in settings, extended settings)
- Force to update the Logitech Firmware
- Let the SBT boot up completely.
- Do another factory reset

Enjoy!

2012-06-25 Thread Triode

Please be aware that kernel #11 will only work with usb2 devices and is
specifically designed for the Tenor 8802l device.

It appears that the Tenor device corrupts the feedback messages it sends
to the linux host.  This firmware contains some code to work around the
specific corruption seen on diego's device.  This may work for other
users, but its possible that we need to make the workaround more generic
to work for other instances of the Tenor device.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...

2012-06-19 Thread diego

Hi there Triode!

Good news: The TE8802L-DAC GETS detected with Windows Firmware on it and
Kernel #9 on SBT.

Bad news: The behaviour is the same, as with EDO only (and its normal
Kernel), and the Linux-Test-Firmware. That means:
- 44100/16 plays OK. When everything is just plugged in, cat... show
values varying slightly around 44100. As soon as everything has plaied
for some time, it stays on exactly 44100k.
- 48000/24 plays OK. cat... always shows 48002
- 96000/24 has two different situations:
when all the gear is still cold: cat... shows values around 176004k.
Sound is very aweful. Just noise, with some small idea of the music in
the background.
after playing for a while: cat... values shown switch between:
88004, 96002, 104002 Hz. Always arount these 3 values with plus minus
2Hz. Sound clicks very frequently music is recocnisable.

I send you the text files with all the cat... and dmesg outcomes by mail
(as here, I can only post two attachments at one time)

To answer your other question: On Windows, the DAC with this firmware
works OK with all frequencies up to 96K (not tested above) and word
lengths of 16 and 24b. 

(And just to explain: After a while of trying out, I found the reason
for DAC not detected in my last tests:  When rebooting, SBT/EDO seems
to search for the last connected usb DAC. If the last usb dac is not
detected, it stays on the DAC not connected screen (maybe you might
modify the EDO so, that it goes by default to the screen, where the
output can be selected).

So... now I am very keen to know the next step :) ! Thanks again for
helping!

EDIT: Just got my I2S - connection - Kit to fit in between my
USB-Interface and my DAC. Bypassing spdif between the DI and the DAC
will allow me to use 192K. So after a bit of soldering and with some
luck that I don't mess up something, I will be able to try 176.4 and
192khz. There is probably little chance that it works better than 96k,
but who knows...

Well first: sorry for being a bit slow, I have never been into Linux,

Now, as far as I understand, your fix in Kernel #9 adresses the
recognition of the (otherwise non-Linux-compatible) Teac. I suspect as
well, that this should be quite similar in my dac. I have the
impression, that the firmwares are provided by the vendor of the TE8802L
chip, which means, that my audio-gd might as a matter of fact have the
same bug in the firmware.

And I supposed as you, that, if it is supposed to work with the Teac
with the original firmware on it, there is good chance it works on mine.
Has somewone seen it working on one of those te8802-based Teac anyway?

So I flashed the original firmware back to the 8802-based digital
interface. When I tried this with your original EDO - kernel, SBT booted
up and showed directly the screen, where the sound card has to be
choosen. And in this case, no usb-dac appeared at all (only analog/dig
or dig only could been chosen from).

The difference now is:

With the 8802-interface with the original firmware installed, it stays
indefnitely at a screen that says DAC not connected.

 EDIT: Stuck for now... I wanted to try the Test Firmware connected to
 a Knoppix Linux CD booted notebook to look, if there is a difference. So
 I needed to flash back my Digital Interface to Liunx Test - firmware.
 And there it got messed up. It stopped in the middle and is not
 accessible anymore since then... I wrote the vendors of audio-gd and of
 TE8802L, but I fear, I will have to send the Digital Interface to
 repair... F-word. So... experimenting will take a bit longer, and
 obviousely, I will think twice before restarting...
 
 LUCKILY, Triode (thanks!!!) did the Test-Kernels so, that it was
 possible to revert everything to stock. I was already fearing that I
 would run into another problem, as rebooting the SBT, it got directly to
 the DAC not connected screen to stay there forever. No possibility
 though, to get into the menu and to reinstall the stock Kernel. So I
 just tried a factory reset, however knowing, that this does not download
 the firmware, just resetting the settings. So I risked to get into an
 even worse situation, as there was of course the possiblity that I would
 get back to the DAC not connected screen, even before having the
 possibility to configure the Network and open the SSH connection, so
 there was a risk of closing me completely out of my SBT. However, I
 think, Triode was wise enough to program his EDO and Kernels so, that I
 got back to the standard menu after resetting, and I redownload the
 stock firmware and now I can reconfigure my SBT from scratch.
 
 At least, the SBT works again, however, async USB is sleeping for now.
 And after experiencing this huge sound improvement yesterday on 44.1k
 and 48k files, using EDO and Kernel 9, I must admit, that I am indeed
 frustrated that I can't continue building on that and even worse, have
 to send in my DI... (whereby shipping to China and back is probably the
 more expensive part, than the exchanging the maybe dead-flashed
 TE8802L-Chip).
 
 
 EDIT #2 : Kingwa from audio-gd helped me... by shortcuting some
 capacitor for a second, something got reset, I was able to flash again.
 That made, that the original firmware worked again on a windows laptop.
 
 Of course, my curiosity forced me to re-flash my DI... to Text-Linux.
 So, the situatin is like yesterday.
 
 With regards to my try on Knoppix, whether there the Linux Test
 Firmware would work correctly: By default, the notebook internal sound
 was activated. And I could not figure out, where to find the usb
 soundcard. I'm a complete Linux Newbie... So I tried the only thing that
 occured to me: cat /proc/asound/cards. The outcome was, that the path
 did not exist.
 
 However happy, that at the end, I did not completely mess up my new DI,
 as initially feard.
 
 EDIT #3: Is there a way to make the Server downsample everything, that
 is 88.2 or above? (but not touching files that are already 44.1 or 48)?
 This would allow me, to keep the async. connection as long as a full
 Linux compatibility is not developped...

Hi - do you have it running in windows or linux firmware at present?  Do
you know if the windows version will work standards uac 2 drivers.  If
you do go back to the windows version, could you test 2 things:
1) Does it work at all frequencies on a windows PC?
2) What does the dmesg show when you connect it to SBT running kernel #9
- even if it is not working, it would be useful to know what the error
messages say.

Thanks for the answer!

It needs a proprietary driver for Windows. I guess, this is not the
standard uac 2, right? Here is the drivers needed:
http://www.audio-gd.com/Pro/dac/TE8802/TE8802EN.htm

1) However, I connected it already to Windows with the proprietary
driver, and the windows firmware installed. I tested it successfully on
44.1k, 48k, 88.2k and 96k. However, my DAC does not support higher
frequencies (I am upgrading it, but don't have the parts yet), so I did
not test 176.4 and 192k.

2) Does it make sense to test that, if it needs a proprietary driver
under windows? As I wrote, when I connect it with the windows firmware,
and reboot, the SBT remains on the DAC not connected screen forever.
Should I try to SSH into it in this state?

I guess the question is whether they claim it works with uac2 (which
windows does not include but osx does and linux does).  If teac claims
it works then I would hope this may.

If you do this - please ssh in when it is in the DAC not connected
state and then let me have the dmesg output.  It may be something simple
which is preventing it being detected.  However its difficult to
diagnose from afar.

Hi there. First test with my Test Firmware. I will do it with the

hoping the workaround will work again. Here comes the dmesg output:

Here comes both information files for 44100 (attachments). This still
works very well. However, cat /proc/asound/card1/stream0 now shows
41000k EXACTLY all the time. Something seems to have changed. I don't
know why, I just listened to music, I have not altered any hardware or
software settings at all. However, when I firt posted, I had just
connected all the gear, it has warmed up in between, maybe this is just
the effect.

To complete it: 24bit / 48khz works nice as well! Here come the logs in

just like it should be, I suppose.

I think you need to find out what the linux special version does vs the
original firmware (have you tried that yet?)  If there is no change to
the frequency shown by cat ever then I am not convinced the async
feedback is working.  

For the 44.100 case it may well be that the two frequencies are close
enough when both devices have warmed up so that the frequencies are
quite close together.  

However I would be expecting small changes in frequency report - not the
large ones you are seeing.  Sounds like something is up with that
firmware.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...

2012-06-16 Thread diego

Thanks Triode, this gives again hope!

TEAC uses TE8802. However, I suspect, that a matching firmware is
needed, to have it even seen by the SBT. At least, this is my
experience. I use a TE8802-audio-gd-Digital Interface. When I have the
standard firmware (made for win and mac) flashed onto the module, and I
connect that to the Touch, the interface just does not show up as
available sound card in the EDO-list of available digital outputs. I
suspect however, that this is more a declaratory issue, than a really
different firmware programming.

Anyway, I will try it out as soon as I can and let you know, if it
worked, with my audio-gd, that has this linux test firmware flashed
onto it.

PS The TE8802-vendor does not reply anymore to my mails, even though I
have written a couple of times.

 If you have a Teac UD-H01 or other device then you may want to try it. 
 It may also be worth trying for other devices using the same interface

 To try:
 
 1) Install EDO

 kernel #9
 
 Please post what demsg says here together with whether you are able to

 bug fixed by the patch does seem a reasonable bug to fix.

Did you look at the dmesg log - its may be that it is the same error as
the Teac - depends on who writes the firmware.  Anyway this looks to
resolve a bug which the Teac definitely suffers from as far as the alsa
list is concerned and if you are hitting the same problem may improve
it..  

I'm wondering if your linux test firmware has other bugs in it for other
sample rates.  So try this with the original firmware too and look at
the dmesg for each case.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...

2012-06-09 Thread diego

Hi there

TE8802L worked with EDO app when using it with a USB-input-module of
audio-gd that is flashed with a test firmware.

However, it does only work correctly with 16b/44.1k - files. Trying with
24b/96K - files crackled.

Details are in this post:
http://forums.slimdevices.com/showthread.php?94512-Announce-Enhanced-Digital-Output-app-USB-Dac-and-192k-Digital-Ouputp=707174viewfull=1#post707174

What is important here:

As an alternative, I wanted to try the procedure in Triods Experimental
Kernels, so I tried the procedure of this thread's first post.

However, I found only the Kernel Update plugin. The USB Audio Ouput -
Plugin was just not there (even though obviously I had correctly entered
the LMS Web settings).

I supposed, that this USB Audio Ouput had been replaced by this EDO -
app. So I tried installing both: Kernel updater and EDO.

Kernel updater showed Kernel #7 and Kernel #8. But when trying to
install them, the download did not even start and I got the message that
the update failed. I assume, they were not found on the server or the
server was down or something.

I also tried installing only Kernel Updater alone (after a factory reset
of course), assuming that maybe, both apps were together in one now.
However, kernel update would not work anyway (only with the EDO-app that
did it as expected, but there is no choice on experimental Kernels).

@TRIODE: How can I help you, developping the EDO-app, in order to work
with TE8802? Can I send you any useful logs or screenshots...?
Unfortunately I do not have permission to send you the experimental
firmware I got.

Best regards and thanks again to Triode for developping this.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...

2012-05-20 Thread JIJ3

Triode, thinking some more about this.

If DIV2 is really set to 1 for both 48K and 96K, then PM must be
different for these two cases (unless external logic changes the master
clock rate, which would seem silly). I assume the master clock for 48K,
96K, (and therefore 192K) is 24.476 Mhz. Then 48K requires a divide by
16 to generate a 1.5298 Mhz bit clock, 96 K would require a divide by 8,
(and 192K a divide by 4). If DIV2 is set to one for 48K and 96K, then PV
would have to be 3 for 48K, 1 for 96K (and zero for 192K, if DIV2 stayed
at 1).

I know you're very busy with the USB work, but when you get a chance you
might want to look closely at the DIV2 and PM bit settings for all
cases.

 I need to try this again - according to the imx35 reference manual there

 would be interested in trying some changes if other people can test the

 I would be interested in your reading of 46.4.2 of the processor
 reference manual - (I think available from the freescale site) - do you
 think changing the div2 stage would result in the right clocks?

With kernal 5, 192K files play at 1/2 speed. They are not downsampled by
the server. With kernal 6, they play at correct speed, but are
downsampled by the server. Does kernal 5 alter this DIV2 setting to
divide the clocks by 2? If so, that may be the problem. My reading of
this section is that DIV2 should be set to 0.

It defaults to and is set to 1 for all cases - kernel #5 should have set
it to 0 for the 192k case but it doesn't seem to work.  I need to look

Switched to async usb last night on the .5 kernel.  Played a 176.4 Neil
Young had a drop out on one song.

Upgraded to your .7 test kernel, played the whole album through no drop
outs.  The drop out might have been a one time thing, like I said I had
just switched to Async USB last night.



I do get a second drop out at the beginning of the first song on a
sample rate change.  Is that the nature of the beast, or is it something
that might be addressed?

Ok I think the drop out was related to not enough juice being supplied
to the hiface.  Got home tonight and the touch crashed as soon as I hit
play.  I backed EDO out and forced installed 7.7.2 and then did a reset
on top.  Reinstalled EDO.  Got audio cutting out at 172 sample rate
again.

Gave the high face more juice with a Y usb cable and hub, and drop outs
went away.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...

2012-05-02 Thread Triode

New test kernel #7 available - to be used to try to find issues with
remaining problematic usb 2 dacs

To try:
1) Install Enhanced Digital Output as normal (see other thread)
2) follow step 3 at the start of this thread to add my usbtestrepo to
your LMS plugin page
3) Install the Kernel Updater app
4) Navigate to Settings  Advanced  Kernel Updater and install test
kernel #7

Test kernel #7 only supports spdif and usb outputs - if you set the
output to analog + digital or default you won't get any output.  It
will also not work without EDO installed.  The purpose of this kernel is
to check whether usb dacs work better with the device drivers for the
internal dacs removed.  These seem to cause problems with aplay -l
maintaining a list of output devices.  I want to validate if this
relates to similar problems seen with some usb2 dacs where the output
device is not seen.

I can confirm that the Eximus DP1 is doing fine with the latest applet
and kernel. However, I still get occasional dropouts with 192KHz flac
coded files, decoding done by SBT. 96KHz files play fine.

 I need to try this again - according to the imx35 reference manual there
 is a divider which should be able to be programmed to change the clock

 would be interested in trying some changes if other people can test the
 impact on the clock outputs.
 
 I would be interested in your reading of 46.4.2 of the processor
 reference manual - (I think available from the freescale site) - do you
 think changing the div2 stage would result in the right clocks?

I certainly have access to the I2S lines and can report the clock rates
that appear there given a test kernal.

I found the imx35 doc you mentioned. Can you point me toward a circuit
or block diagram of how this device is connected inside the Touch?  I no
longer have the device open.

Yes I need to make them available - I've been more focused on getting it
to work than posting the patches.

Sorry misread your previous post - happy to email you the patches if you
PM me an email address (prior to making them more widely available)

I think the rDac was the one which had a problem with the syncinterval -
it asks for a value which is too high for the linux usb scheduler, so my
code reduces this.  It really depends on the age of your ehci-sched.c as
it looks to me that more recent versions of this may allow the syncpipe
to be scheduled.  I have kept it as per the Logitech version with some
minor patches to the sound/usb code to change the sync interval:

This is from snd_usb_set_format_quirk() in sound/usb/quirks.c [which is
post the refactoring of sound/usb so depends on the age of your kernel
whether you have it]

Code:


  + // check for long syncintervals which we can't schedule and reduce
  + if (snd_usb_get_speed(subs-dev) == USB_SPEED_FULL  
subs-syncinterval = 6) {
  + printk(async usb sync interval too high reducing %d - 6\n, 
subs-syncinterval);
  + subs-syncinterval = 6;
  + }

My GT40 came and I tested with the EDO app, and all fine, with or
without Hama USB hub.  Serious listening testing will have to wait, but
I'm up and running with USB DAC, which is great.  

Sadly, with Touch Toolbox 3.0 on top, sound was very garbled, with or
weithout hub, so I've posted that result in Klaus' TT thread in Audio
Asylum forum. 

So I'm mainly happy, and delighted with the ease of setup of the EDO
applet.  Triode, very many thanks.  Let me know if you want any further
details for your success list.

My Furutech GT40 should arrive on Monday and I will report back when set
up. I just received a technical data sheet and understand that it's a
USB Audio class 1 with adaptive USB based on Tenor TE7022L USB chip
limited to 24/96, so if I understand correctly should not need external
USB hub (though I have one on hand just in case).

I use a Wireworld Platinum Starlight USB cable to connect the SBT to the
Antelope Zodiac Gold and the improvement is quite audible when compared
with the stock cable which comes with the Zodiac Gold.

Does it matter which way round the USB hub is connected? (main plug into

SBT is the host and the dac is plugged in as a usb device to the hub.
