sound card detection

Ok, a guy has a computer, I have no clue what is in it, but it's definately acting weird. When I run RHL soundcard detection, it finds and runs the card just fine, but I don't get any system sounds or CD audio. Why?

What did you try to play CD audio?
What do you means you don't have system sound? I suppose that you hear nothing even a sytem beep, Right?

I assume that RHL = Fedora Core?

To find out what is in it, open a terminal, and do the following.

1: run lspci. Look for something like "Multimedia audio controller". That is the type of card he has.
2: type "ls /dev/snd". If you see something like this, then the audio controller has been detected by alsa.
h2so4 snd # ls /dev/snd
controlC0  controlC2  pcmC0D0p  pcmC0D2c  pcmC1D0c  pcmC2D1c  timer
controlC1  pcmC0D0c   pcmC0D1p  pcmC0D2p  pcmC2D0c  seq
3: If that's all good, make certain that the sound isn't muted. type "amixer" and look for something like:
Simple mixer control 'Master',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Front Left: Playback 0 [0%]
  Front Right: Playback 0 [0%]
See how FL and FR playback are at 0%? Type "alsamixer" to adjust the faders and unmute. Ping the thread if you need further assistance.

Thank you for your time,
Frank Russo

you go to the following link and there u see

1. Efficient support for all types of audio interfaces, from consumer soundcards to professional multichannel audio interfaces.
2. Fully modularized sound drivers.
3. SMP and thread-safe design.
4. User space library (alsa-lib) to simplify application programming and provide higher level functionality.
5. Support for the older OSS API, providing binary compatibility for most OSS programs.

ALSA is released under the GPL (GNU General Public license) and the LGPL (GNU Lesser General Public License).

We need users to use, test and provide feedback, programmers to work on low level drivers, writers to extend and improve our documentation, and application developers who choose to use ALSA as the basis for their programs. If you are interested, please subscribe to a mailing list.

We welcome all constructive ideas, opinions and feedback!
