I have built-in C-Media 8738 sound on my motherboard and am using the alsa cmipci module, which installed and works well--EXCEPT only the right channel is working. No sound from the left speaker at all. The speakers are fine, as is the hardware (it worked fine with an unnamed proprietary os). What am I doing wrong??

Thanks in advance for your assistance.

P.S. This is now fixed, thanks.

Hi there.

Try to run envy24control (I believe it is in alsa-utils or alsa-tools package) and look at the output of the channels and to what is assigned to them.

Sorry if I'm sayng something very wrong (I don't know if envy24control works for every audio card).

The envy4control utility doesn't work with my sound hardware, but thank you for replying.
