Re: How to unmute the sound?

["Michael Yang" <michael.yxf@gmail.com>]

Here is the error message when I open the audio file:

[AO_ALSA] alsa-lib: confmisc.c:768:(parse_card) cannot find card '0'

Could not open/initialize audio device -> no sound.

I have tried uninstall alsa driver and re-compile and reinstalled it for several times, the problem still exists.

Could any one help?

Thanks.

probably you should have tried to solve this problem instead of
creating a new problem over the top. Whatever caused the first problem
is still around and may be the reason your recompiled drivers aren't
working.

please provide the output of

lsmod | grep snd

and the relevant portion of

lspci
