Funny, before reading your message, that's what i ended up doing.
The mic input seems to be working fine, although it seems very counter-
intuitive to feed line-level signal into a mic input.
I was finally able to watch TV using MythTV with sound, and i am
recording a show now to make sure all is good.
I think i hear some popping noises when watching TV. I'm not sure what's
the cause - they don't seem to be overload pops, but i cannot be sure.

Wow, that seems like a great idea!
Anything special i have to set in /etc/modprobe.conf?
Here are the dsp devices that i have:
# ls /dev/dsp*
/dev/dsp /dev/dsp1 /dev/dsp2
The first one is the Audigy2
The second one (dsp1) is the onboard AC97 soundcard, which seems to be
pretty lame (couldn't turn on capture, seems quite bad anyway). I think
i'll disable it.
Could it be that dsp2 is the TV card? I think i remember telling MythTV
to use dsp2, but i think it gave me an error (although i could be
wrong). The Gnome mixer does have three tabs, the first two related to
the soundcards, the third appears to be related to the TV card, but i am
I do see a snd_bt87x module loaded. Could that be the "btaudio" module
Any other tips related to this trick? :-)
Newbie question: if i tell MythTV to record sound straight from the TV
card, how will it know to wich card to play it back, so i can hear it in
the speakers connected to the Audigy?
