Sound Card not working (resolved)

I've got a new system, and the integrated sound card on it isn't working, so I swiped the PCI sound card from my old computer and inserted it.  And it's not working.  I've pretty much tried every method on the troubleshooting section of ALSA's page on the wiki, without any luck.  And yes, this includes unmuting and setting the volume of the sound channels.

Re: Sound Card not working (resolved)

I don't think I'm advanced enough yet to try to compile the kernel.

Re: Sound Card not working (resolved)

After installing hwd and running the command, I get this as my output:

8086:266e Multimedia audio controller: Intel Corporation module: snd_intel8x0

Seems like it's not detecting my sound card.  About an hour ago, I switched around a cable on the sound card in an attempt to fix it.  However, I can't help but wonder if that only made things marginally worse.  I'm going to shutdown my computer for a moment and put the cable back in place.

Anyways here's what lspci says about my sound card:

04:00.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10)

EDIT: Done.  Running "hwd -e|grep snd" still returns the same results.  However, if I run it without the grep command, the sound card is listed as:

13f6:0111 Multimedia audio controller: C-Media Electronics Inc module: C-Media PCI

Re: Sound Card not working (resolved)

I already knew that I had two cards.  I added in the second one because the integrated chip wasn't working.  Anyways, here's the results of lspci -nn:

Re: Sound Card not working (resolved)

First off lets decide on which one you want to get running.. the onboard sound or the PCI sound card.  I say we attempt the onboard (unless you have a reason for wanting to use the PCI card)

hwd seems to stay snd_intel8x0 is the module for your soundcard. I use the same module here for onboard sound and it work fine.

Post your:

lsmod | grep snd

In it you should find the snd_intel8x0 module listed.  If not then it's not being autodetected for some reason. To load it manually.

modprobe snd_intel8x0

Then try your sound.

Re: Sound Card not working (resolved)

The module of your "C-Media Electronics Inc CM8738 [13f6:0111] (rev 10)" is: cmipci

Re: Sound Card not working (resolved)

Guess what?  Sound plays if I unmute the headphone mixer.  I don't know why it's doing this, but I think I would rather have the sound playing through the master mixer.

Re: Sound Card not working (resolved)

Silly question: Are the speakers plugged into the headphone jacks instead of the speaker jacks? tongue

Re: Sound Card not working (resolved)

I used to have this problem on one of my former motherboards..

The fix involves using ac97_quirk as a module option.  Changing that setting will help to swap the channels but I don't remember the specifics of it.  All I remember is that you add a line to /etc/modprobe.conf with that option.

Search for ac97_quirk in the forums and google and the solution will turn up.  If I remembered exactly then I would tell you.. Hope that sets you on the right path..

Re: Sound Card not working (resolved)

Found it!   Placing this line in /etc/modprobe.conf seems to have done the trick:

options    snd-intel8x0 ac97_quirk=1

Re: Sound Card not working (resolved)

Good call, Zero, and glad you got it fixed,Falcata!
I just knew you'd get fixed up.
I've seen this issue twice now...I must remember to suggest this in the future...
