Summary:                    CMedia 8768 Support
Description: 
I've recently built a new computer with an on-board CMedia 8768 chip.  This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new.  Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru).  Here is what I see though:

The card is recognized in /proc/asound as a CMedia 8738M6.  However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).

Any advice or comments would be appreciated.  I'd be happy to help if you
think there is a possible fix.

I tested this board (Soltek EQ3801) and found that the on-board codec
cannot be accessed in DOS. It cannot betested by our DOS diagonal program
, but a add-on card can.

I guess that the BIOS doesn't initialize the on-board codec correctly.
Does ayone has this kind of problem with another mother board?

The thread brought up cltien's note here about the codec not working. The
response from Soltek:

Actually some days ago, one customer reported to us that onboard audio of
EQ3801 does not work under "Fedora Core 3 Linux". So now our BIOS engineer
and C-Media support are working on this issue. If there is any progress, I
will let you know.
