Re: [Alsa-user] Analog line in output via IEC958?

How can I get this to work? Antony, I don't know of a solution for you under linux, but perhaps this will jog the memory of someone who is more knowledgeable about such things... Under Windows, with my nvidia sound, the nvmixer app used to have an option digitize input. I see this option is gone now, so I wonder if nvidia had problems with it and nuked it, or if they just hide it somehow. My desktop setup used to consist of two computers, one monitor and a pair of digital speakers. One of the computers would output analog audio to the second, which would digitize it, mix it with its own audio and output to my digital speakers. I don't recall any delay, but never really paid attention to those details. If there's a switch for it under windows, and it is a function of the chipset rather than the software, is it possible to turn it on under linux? -Gordon -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

[Alsa-user] [alsa-user] Weak left channel sound
Hello everyone. The left channel on my laptop and desktop seems to have stopped working properly under Linux. I've tried two different flavors of the same distro, ubuntu 710 and 704. Here's a summary of the problems: Laptop: 704 = weak left channel, 710 = no left channel at all Desktop: 704 = normal left channel, 710 = weak left channel By weak, I mean the volume is considerably diminished compared to the right channel. It does not matter what the source of the sound is (system sounds, xmms, flash player, etc) By no left channel I mean when the balance control is set to 100% left, no sound can be heard from the system at all. I've checked the volume control under gnome, as well as alsa mixer and verified that both channel volumes are set the same. The laptop is a Centrino Duo based chipset and processor, the desktop is a Core 2 Duo based chip and processor (both of the 965 variety I believe). The sound chipset is reported as Intel HDA, not sure what version or model. The laptop is a HP Compaq nc6320 and the desktop is a Dell Optiplex GX745. Any suggestions of things to try, do I need to post up pages and pages of output from tools such as lspci -v ? Gordon - This SF.net email is sponsored by: Splunk Inc.

[Alsa-user] Shuttle SN41G2 Optical spdif
Hi Everybody!
I'm pulling my hair out over here. I'm stuck on getting my sound working!
setup:
shuttle sn41g2 v1 (fn41 v1 mobo), 512m ram, 120g pata hdd, athlon xp
2200+ cpu, fedora core 6, 2.6.19 (stock) kernel, all the latest yum
updates
this shuttle has the overly complex nvidia SoundStorm2 sound system in
it, the one with all the fancy Dolby Digital codecs. The motherboard
has support for both coaxial and optical spdif outputs, however only
the optical output is actually connected to anything.
I've tried various /etc/asound.conf files, from simple to complex.
I've tried having the IEC958 mixer control muted and unmuted
I've tried adjusting the volume on the IEC958 Playback (it has 3 levels)
I've tried 44100 and 48000 sample rates, as well as no resampling at all
I've tried playing a dvd: mplayer -ao asla:device=spdif -ac hwac3 -
the receiver lights change to indicate a dolby digital stream is
detected, but no sound
Under windows, of course, it works fine :-(
__Does anyone with a Shuttle SN41G2 have their optical output working?__
Thanks,
Gordon

Re: [Alsa-user] Surround sound via optical spdif out
just to chime in ... I have a similar pioneer look on your display, where the little digital / analog display box is. when receiving a encoded pcm bitstream, the display will show: DOLBY DIGITAL or DIGITAL DTS depending on the encoding used... when a normal non-encoded pcm is received the indicator will just read DIGITAL gordon On 10/13/06, Nathan A.

Re: [Alsa-user] OT: Recommendations for sound recording with SPDIF
Greetings, If you can find one you like with a coaxial sp/dif input (or even just a sp/dif in header), it is a small matter to convert optical to coaxial. If you're handy with soldering, you basically need a photo transistor (toslink receiver) and a few other components ... or if you prefer a finished product, toslink to coax converters are normally around $20, even cheaper if you shop I bit ... I think I paid around $15 for mine, but it's the other way around, coax to toslink.

I already have one doing the job, an Audigy2 Platinum, which I could get another one, but I'm looking to see if there's a cheaper alternative, maybe even something that doesn't require a 5 1/4 slot, that would accomplish the same thing.

Re: [Alsa-user] OT: Recommendations for sound recording with SPDIF
I'm pretty sure you won't be able to do that.. for cards that have both options, they just have a Toslink to Coax converter built on the card, and feed the coax signal into the dsp. you could probably have both sources connected, but not actually use them at the same time.

Hopefully I can record through both my optical and coaxial at the same time on the SB Audigy2. That'll be the end of the research I need to complete.

[Alsa-user] on the fly routing
is it possible to (re)route an audio stream (source) such as mpg321 on the fly to one or more sound cards? by on the fly, I mean, without interrupting the source, ie ctrl-c and reissue the command with a different output device I've designed an digitally controlled analog signal router, but it's looking like it'll cost $100 to actually build a few (pcb is very complex and costly to have fabricated in small quanity) ... so if I can do it in software, great! thanks for any advice!

[Alsa-user] ES1371 and rear speakers
Does anyone on the list have an ES1371 (Creative or Ensoniq AudioPCI or SB128). I'm wondering about its capabilities. /proc/asound/devices shows it has two playback devices and one capture devices. [EMAIL PROTECTED] wav]# cat /proc/asound/devices 0: [0- 0]: ctl 8: [0- 0]: raw midi 17: [0- 1]: digital audio playback 16: [0- 0]: digital audio playback 24: [0- 0]: digital audio capture and according to what I've read on google, the LINE-IN jack doubles as the rear line-out. however, speakers (amplified) connected to the line-out produce no sound I try sending a wav to hw:0,1 (should that be the rear channels?) and it shows up on the front speakers. Same thing happens when I send a wav to hw:0,0 is there a command or something I need to issue, to enable the rear outputs? the datasheet for the hardware codec (akm4531) shows two DACs, one with a dedicated line level output and a mixer output, the other with only a mixer output ... this would seem to match up with some stuff I've read on google about the rear speakers being of 'uncontrollable' volume (since there is no gain control indicated in the datasheet) I also tried doing it this way: [EMAIL PROTECTED] wav]# aplay -D rear tada.wav ALSA lib setup.c:548:(add_elem) Cannot obtain info for CTL elem (MIXER,'AC97 2ch-4ch Copy Switch',0,0,0): No such file or directory aplay: main:508: audio open error: No such file or directory I have added amixer shows me, and the very end of this message, since the output is very long.

[Alsa-user] divided multichannel
Greetings! I'm new to the list, and although not new to alsa, I'm new to how it works ... in the past, I've just relied on it to do it's magic, auto-configured as it was during the install :) Anyway ... my goal, lofty perhaps, is to have multiple room music from my linux machine, that is running 24x7 as a file server. I only have one PCI slot free in the box (scsi and sata cards take up the rest of the space), however, I thought, fear-not, my SB live has 3 stereo output channels. I searched google a little, and this list archives, and I have found this very question asked several times, but no one ever offered a response. So I take it this must be harder than it sounds? My questions is ... can I split up the 3 stereo outputs, so that I can use each as its own 'plain' stereo sound card... perhaps listening to different MP3s or Shoutcast streams on each output. Each output would be whisked away to remote amplifiers serving separate rooms Thanks in advance for any insight and guidance!
