Acer extensa 2900 audio problem detection

man1979 · 08-22-2005, 10:16 AM

Hello to everybody,

I have the following problem,

I have an acer extensa 2900 and my audio card
when I test the sound for wathing if the card is working correctly i have the
following message:
I write system-config-soundcard and then
follows the below message:

amixer: Unable to find simple control 'PCM-2',0

amixer: Unable to find simple control 'DRC Range',0

The strange think is that i can play some wav files with xmms but
i dont hear anything.

Does anybody know about this problem?

I would appreciate any help.

thanks

Hi, first of all, study the output of the commands:

Code:

lsmod

and

Code:

lspci
