I have a MDK 9.2, and btaudio can be inserted at any time, does not  
matter before or after bttv (in fact I load btaudio from the rc.local  
script file (just added "modprobe btaudio" as the last line of the  
file), which means way after bttv; I do that because the real issue is  
to load btaudio AFTER the driver of your sound card, because else it is  
a mess).
BUT having the good chip for the sound on your card is not an insurance  
that btaudio will work. It seems that some cards have the good chip but  
badly wired (this is in the doc file of mythtv). So check if your card  
could work with btaudio.

This looks good, I have the same thing.

I don't think that kmix controls the mixer of btaudio.
So the test it : using eg xawtv, select a channel, and try listening on / 
dev/dsp1, you should have the sound of the channel you're watching  
(actually I had some problems with aplay, and I used sox for my test,  
anyway this does not matter as soon as you obtain the sound  
corresponding to the image).

Good luck.
