Hi nandod2, Welcome to lq. Have you ensured that you don't have sound muted? try running one of your mixer applications and see if it will get you some sound. If that doesn't work or you've already tried it, please post the output from
Code:

/sbin/lspci -v
/sbin/lsmod

Let's make sure we've got the right card and the modules are loaded.
Good luck. ;-)

duo post sorry

Is there another device plugged into a usb port? These look out of place.
Code:

snd_usb_audio 79553 0
snd_usb_lib 19777 1 snd_usb_audio
snd_rawmidi 26817 1 snd_usb_lib
snd_hwdep 13125 1 snd_usb_audio

Is your user in the audio group, it may be a permissions problem?
Good luck. ;-)

nandod2 09-12-2007 09:17 PM

how do i check that?...

I should have been more clear, do you have anything physically plugged into a usb port? Any device at all, webcam, external sound card, printer, etc. Have you tried alsamixer from a terminal?
Good luck. ;-)
