Hmm...
Alsa 0.9.4, installed on Gentoo linux, kernel 2.4.20.
System - IBM Thinkpad A31p
Driver - Intel8x0
My system thinks my soundcard is:
shiro simon # grep audio /proc/pci
Multimedia audio controller: Intel Corp. 82801CA/CAM AC'97 Audio (rev 2).
Basically, everything appears to be working fine. All the modules are loaded.
Alsasound starts without error. aplay plays wav files without error. ARTS
runs without complaint. The whole system seems fine, except I can't actually
hear anything. No sound is produced at all. It's like the sound output is
muted, only afaik it isn't... (I tried turning everything up with alsamixer)
Perhaps someone who understand it all, can browse my output from amixer to see
if there's something not switched on that should be?
Sound used to work before I did a reinstall.
Soundcore is compiled as a module. everything else sound-related is off. Here
are the sound-related modules I have loaded.

I have been through alsamixer and unmuted everything with the 'm' key. I have
turned everything up to 100%. Here is the output of amixer:

Everything plays without error. The call to aplay "waits" for a sensible
length of time (the length the file should be) before quitting.
[EMAIL PROTECTED] simon $ aplay /usr/share/frozen-bubble/snd/newroot_solo.wav
Playing WAVE '/usr/share/frozen-bubble/snd/newroot_solo.wav' : Signed 16 bit
Little Endian, Rate 44100 Hz, Stereo
I have tried both with external speakers connected, and without (to play
through the speakers in the laptop) - neither produces any sound.
I have tried 'cat /dev/audio' - and I get continuous output. It looks like the
output changes when I play a file, but it's hard to tell. My skills at
reading garbage and taking meaning from it aren't the greatest in the world.
I can't think of anything else. It's not broken speakers because I've tried
internal and external. The modules are loaded. The sound is unmuted and
turned up. Everything plays without error. NO SOUND COMES OUT!
Anybody have any ideas how to get it to make some noise?
Thanks,
Simon
