[mythtv-users] bttv, alsa, cmipci

[Greg Donald]

I am having issues getting sound to work in MythTV.  I installed ALSA, 
and it works great in other audio apps like xmms, kde event sounds, etc.

I have the CMedia chipset:

$ cat /proc/pci |grep audio
     Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 16).

and the Brooktree tv tuner:

$ cat /proc/pci |grep Brook
     Multimedia video controller: Brooktree Corporation Bt878 Video 
Capture (rev 2).
     Multimedia controller: Brooktree Corporation Bt878 Audio Capture 
(rev 2).


I think I have all the required modules loaded:

Still, no sound for TV no matter what I try.  Any ideas?

Thanks,

Greg
