[mythtv-users] MythTV is not capturing audio?

[Chad]

Hi!

I have been plugging away day and night trying to figure this out, but
can't come to any good conclusion.

When I view a card from xawtv, I can hear the audio and see the video.
 But, when I throw Myth into the mix, I can no longer hear any audio. 
I have the capture set to the Line-In, which is where the cable is ran
to from the card's audio out.  The tuner card is an saa7134 deal, I'll
post up lspci at the end for completeness.  The audio card is a cmipci
(C-Media) card.  I grabbed a handful of them because the price was
right and I knew they were supported with Alsa in Linux.  Just to make
sure it wasn't just an audio out problem, I played back a captured
program from before adding this card, and it works just fine.  This is
a second tuner/second audio card in my system, so I've troubleshot all
combinations, and it seems that it all comes down to audio capture
from this particular card.  Any combo works in xawtv, and any combo
provides video, it's just that myth doesn't seem to be able to record
from the audio card's Line-In (capture) port...

Any suggestion are very welcome.  Here's my lspci output:
