Re: [Alsa-user] mp3 trouble - help from here?

It's installed now, but Xine and Banshee are still looking for an mp3 decoder. The man page for lame shows it to be a converter of other sound files to mp3. More a producer than a converter. LAME's the (kind of) program that produces MP3 files. It encodes raw, uncompressed digital audio such as found on CDs for example (and sometimes also known as PCM) to the compressed audio format MP3. As a bonus, it also accepts MP2 or MP3 files as input but that's just for convenience (and a bad idea -- see below). Since I can't hear the mp3 files I have, I don't see how this helps. Man lame also mentions mpg123 and madplay. Neither are in the Suse10.2 distribution. These appear to be mp3 players. Yes, those are command line MP3 players. Amarok, XMMS, AlsaPlayer and many more players are also available for the GUI. What is the decoder Xine and Banshee think they are missing? Try if this is useful: http://amarok.kde.org/wiki/MP3_on_SUSE_Linux_10.2 More generally though, the answer's no idea, as this is completely distribution specific and moreover not at all related to ALSA. See, the trouble is -- MP3 is a proprietary, patent encumbered format for which (sometimes) licensing fees have to be payed to some unclear number of parties and as such, free distributions have trouble supplying MP3 support out of the box. The trouble you are having now is the kind of trouble usage of these and similar formats land people in. Rene, I'm thinking that mp3 files would need to be converted to Ogg Vorbis? No, I wouldn't really advice that. Both MP3 and Ogg Vorbis are lossy compression formats, which means they both leave out some of the information from the original uncompressed source audio. Exactly what and how much they leave out is what makes them different. Obviously, if your source form is one lossy format, any re-encoding to another lossy format could only leave out more which means you should expect to end up with a worse sounding file. Generally it won't be bad, so for casual use transcoding MP3 to Ogg Vorbis can be okay, but as a rule you shouldn't. Always encode directly from the source, which normally means from the CD. If you don't have the source, chances are fairly high the MP3 was illegally distributed to you in the first place, so you don't get to complain about anything and nobody cares about your needs anyway :-) Can OV do that or would that conversion require another application in need of an mp3 decoder? Dunno what OV is, but as said, I'd not transcode anything. The normal application to encode from PCM to Ogg Vorbis is oggenc. Really off-topic this, so I hope the link above is useful. If not, you're best of following up to some SuSE specific list/forum. Rene. - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Re: [Alsa-user] alsa buffer size
Thanks for replying. I am writing an application that is generic enough to a number of different drivers. If thats possible! I am trying to achieve a 2 second of buffer for a number of different sample rates. This means that for a sample rate of 44.1KHz I require a buffer size of 88.2K frames For all the different types of sound cards that I have used I havent seen a buffer size 16K frames : ( I have noticed that various drivers have certain behaviour which makes writing a application that is generic for all drivers very difficult. For example for an intel chipset I have found that the driver was very versatile and allowed me to choose various period sizes for different buffer sizes. Whilst the driver for the CS4299 chipset, although allows a buffer size of upto 16K the period size has to be half that value. Therefore this makes it impossible for me to use with the ALSA callback mechanism, which I need to use for the design to work! By the way how do I find out which driver is assigned to a chipset?

Re: [Alsa-user] alsa buffer size
I have successfully increased the amount of buffer by writing a new value into /proc/asound/cardX/pcm*/sub*/prealloc. For a mono .wav file I was able to successfully change this from 64 to 512. I was really happy with this. I presume this value is in the units of kBytes? And that this value needs to be 2 to the n. ie 16,32,64 etc? Dont know why but I couldn't change this to 512, do you? I also tried this change on a stereo .wav file but it didnt scale as I thought. In fact I could only set this to 32! Which doesnt make sense. Do you know why?

[Alsa-user] Front Output Jack problems with AD1986A/M5461
Hi, I'm using the latest ALSA version with Ubuntu Fiesty and I can't seem to get my front audio jack on my computer to work. I have an ASUS A8R-MVP mobo and my case has some jumpers to connect a front audio output (and input but I don't use it) to my mobo. The rear jack that is part of my mobo works great, but the front one never gets any sound. Works find under my WinXP boot, but not under Linux, so I'm pretty sure it's some ALSA setting I need to change. I'm somewhat comfortable with Linux, but never had to worry about sound issues before now, so not sure what information would be useful here, but here's a stab at some useful stuff $ cat /proc/asound/cards 0 [M5461 ]: HDA-Intel - HDA ULI M5461 HDA ULI M5461 at 0xcedf8000 irq 22 $ cat /proc/asound/pcm 00-01: AD198x Digital : AD198x Digital : playback 1 00-00: AD198x Analog : AD198x Analog : playback 1 : capture 1 $ cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.14. Compiled on Aug 30 2007 for kernel 2.6.20-16-generic (SMP). Ideally I would love to play the front port at an attenuated volume compared to the back port, as I usually have headphones plugged into the front and speakers in the back which can get a bit too lound on headphones. But just getting sound out of that front port in any form would be great. Thanks in advance. -Kevin - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems?

Strange. Please show the contents of /proc/asounc/card0/cmipci.
Since I just bought that card and never tested it somewhere else:
Could this just be a hardware problem / defect? From a look at the
driver's sources, it seems that this mixer element directly maps to
the low bit of CM_REG_MIXER1.
Indeed. (This is why I asked for the cmipci file and not the cards
file, to see how the mixer control affects this bit in register 0x24.)
I didn't (yet) check that card in a Windows machine to test it with
vendor's drivers, but I really guess it's kind of a hardware problem.
Just out of interest, I ordered another, similar card (Ultron
Octosound 7.1, lspci: C-Media Electronics Inc CM8738 (rev 10),
/proc/asound/cards: C-Media PCI CMI8738-MC8 (model 68))
Plugged all in, fired up speaker-test, everything seems to work right
out of the box.
Fired up an alsaplayer to play some FLAC. Switched on Four Channel
Mode for a test, which nicely adds sound to the rear left/right
outputs.
After the FLAC ended, I fired up speaker-test again (and of course
switched off Four Channel Mode.) This time, it's different than
before: front center/LFE, front left/right and side left/right are
okay, but rear right/left are highly distorted.
Unloaded/loaded the module once, but that didn't fix it. Powercycle
(did also remove the power cord to really let it loss its power) fixed
it. So I guess there's still a state-handling problem somewhere?
Ran another test, right after another power-cycle:
* speaker-test -twav -Dplug:surround71 -c8
- All okay.
* alsamixergui
* speaker-test -twav -Dplug:surround71 -c8
- All okay.
* alsaplayer 04_my_immortal.flac (for some seconds, Ctrl-C'ed out)
- Plays fine
* speaker-test -twav -Dplug:surround71 -c8
- Distorted sound on both rear {left,right} speakers. All
other channels are still okay.
Maybe that rings a bell somewhere?

Note also that debian is the worst distribution to use if you want to support the latest hardware. They purposely trade off support for stability. That may be a good tradeoff for some, but support for sound hardware is not one of the places. Yes, I know debian is not the best. But I know it better than others and so I use it. I downloaded 64 Studio debian, and will give it a try as soon as possible :-) What distro do you use? Which is the best for midi work? I tried dyne:bolic and pure:dyne, but it's hard to compile new drivers there... Despite that I think they're great. If it comes to the drivers, the patch Clemens Ladisch has provided link to, worked well. My interface now works. But unfortunately I can't use it due to problems with real time - when I do some work with interface (enter notes wit mouse etc), there are delays. Really nasty.

[Alsa-user] Best soundcard to buy for Linux
Hello! I'm searching for the best soundcard to use with a JavaSound/VoIP application on Linux. I even have to mix in noise/clips with the VoIP packages received on the PC that will render the sound. So I thought better to go for a card that has HW mixing capabilities, which let me open more than one SourceDataLine (one for VoIP, one for noise and one for clip...) and let mixing be done at the hardware. I got hold of an old Creative Audigy 1 card, which really gave me great sound, as opposed to the new Creative Audigy SE cards with no HW mixing. However, cards with HW mixing is really not easy to find on Linux. Creative seem to have stopped producing the Audigy HW mixing cards. All I found except that was the Mia MIDI card, but that had only passive mic input (had to have a preamp on those mics!). If my mixing can't be done in hardware, does any one have a good recommendation on well performing single/double line I/O sound cards supported on Linux? Best would be with drivers supporting opening more than one SourceDataLine on the same mixer. Best regards, Helge Fredriksen - This SF.net email is sponsored by: Splunk Inc.

Re: [Alsa-user] Best USB based XLR3 interface to buy?
Is there a list of still produced USB based XLR3 microphone interfaces that actually work with linux/alsa? I would like to buy a USB 2.0 based soundcard that allows high quality input from an XLR microphone. Preferably two XLR3 inputs for stereo recording. Any recommendations? For ones that work, or even ones that are known to NOT work, so I don't get one of those by accident.

Is there a list of known devices that work? Or do I just need to bump through all of the entries in the soundcard matrix and hope I run into a supported usb 2.0 device that has stereo XLR mic interfaces?

[Alsa-user] Audio Hardware for multichannel output
Hi - I've been looking around, but I can't seem to find a recommended list of hardware for use with Alsa and multichannel output, and I'm wondering if anyone on the list has hands-on experience with hardware that works reliably in this application. Specifically, I'm looking to drive between 16 separate mono outputs from a single PC, using a custom application that I'll write in either C++ or java. It looks like alsa allows you to bind multiple consumer-grade cards as a single device for this purpose, although I'm just as happy (and would probably prefer) to buy a rock-solid, purpose-built, commercial-grade piece of hardware. I'd rather pay a little extra and avoid the nightmarish headache of trying to get long-term consistency out of four soundblasters. If you're not comfortable endorsing a particular venue or solution on the list, please feel free to mail me directly. Thanks in advance, Jeromie Clark - This SF.net email is sponsored by: Splunk Inc.
