[mythtv-users] no sound with C-media 8738

[cmisip]

I could not get my cmi8738 to work well with mythtv either.  the audio
was very weak and with some distortion.  I gave up on it and bought a
second sound card SBLive 5.1.  I now use the SBLive for mytht and the
cmedia for the rest of the multimedia apps in linux.  the cmedia does
well for that, and i can record from the mic in (I use it for
Misterhouse).
