Yes, I made sure that the line-in is set as the
record-source and is muted. Tvtime and xawtv work
properly when I unmute the line-in. Another way I'm
able to get hear the real-time audio is increasing the
volume level on "AC97" control, with the
"capture"(which I believe is AC97 capture) also
selected as a recording source. The funny thing about
AC97 is that it continues to play even after I exit
out of mythtv !
Essestially, I'm not able to get the audio
captured/buffered. Any ideas on how to debug/fix the
problem further?
Thanks

Does your TV card support snd-bt8x8?

Have you monitored your sound mixer settings whilst
playing TV and
making sure your line in is set up to record/muted and
your ouput
devices are set to sufficient volume?
