hello,
Some time ago ( long time ) i managed to get the sound working. But now can't figure out what's wrong:

Code:

lsmod | grep snd

I'm not sure if this will help but you could try.
You might need to configure ALSA with the following commands:
su
ENTER PASSWORD
alsaconf
alsactl store
alsamixer

Play around with the volumes in alsamixer and make sure your sound device is not muted.

Hope this helps.

hmm i can't locate the alsaconf util.
but alsamixer seemd to show that all channels are @ their max....

just in case this maybe relevant:

Code:

rpm -qa | grep alsa
alsa-utils-1.0.17-1.el5
alsa-lib-1.0.17-1.el5

i'm trying to run "alsacard" but it doesn't produce any output

BTW, you said " make sure your sound device is not muted", how do i check that?

Geraldsmod · 10-02-2009, 02:19 PM

That's another way of saying check if your sound bars in alsamixer are all the way down.

Thanks.

yeah, i tried that too, but it was asking to soundcart number (id?). And i have no idea how to get that number

I have some weird problems with my ALSA too.
Sometimes, the sound will decide not to work and I have to turn my computer off for awhile to get it to work again.

If worse comes to worse, backup your files and re-install your distro.
