Soundcard detected but no sound
 
Hi,

system-config-soundcard detects my onboard audio VIA8235 but I have no sound. I have unmuted all volumes in gnome-volume-control and checked that my speakers work by plugging them into my mp3 player.

What can I do to find the problem?

Thanks.

Are the sound modules loaded? What is your kernel version?
First update your kernel, then post the results of
1) /sbin/lsmod | grep snd
2) yum list installed | grep alsa
3) /sbin/lspci

Also try '/sbin/modprobe'

Here is the output from each. I can't find any obvious irregularities, except for the fact that system-config-soundcard lists two available soundcards (both VIA8235). The output of aplay -l is at the bottom of the post.

No one knows a solution to this problem?

phyrko 03-01-2007 03:43 AM
smOk3, in the end I installed an old PCI soundcard I had lying around and that worked fine. I guess there was no definitive way to tell that it wasn't some weird problem with the hardware not working properly.

Hope that helps.

Thanks for the suggestion but I am using a laptop and have not messed with the internals much...not sure if I can replace the sound card, but I heard that VIA isn't always 'linux-friendly', so I am not sure if sound will ever work unless I learn how to program device drivers. Thanks for your help though.
