I'm having exactly the same problem.  I'm using a Wintv go card. Athlon 
2200+ on a KM266 chipset, VIA 8233 audio, using MythTv 0.12.

On another subject, I also tried to get btautio module loaded but when 
running make it says:

"The present kernel configuration has modules disabled.
Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled."

I know this isn't the case thouth because I load the alsa module, so I 
don't know what the "makefile" for btaudio is basing it's conclusion on.


Any help is greatly appreciated.
