[mythtv] Sound Mode Selection

I have an AVerMedia Stereo tuner card and the bttv driver seems to
have a bug. The bug is that on channels that have SAP audio, the
auto mode selection seems to select some odd mode where the main
audio is on the left channel and SAP is on the right channel. When
I'm using xawtv, after hacking the bttv driver some, if i select
stereo, I now get the normal stereo mode I would expect.

MythTV seems to just leave the audio mode on auto as it probably
should. How would I make it select VIDEO_SONUD_STEREO mode? I tried
putting a VIDIOCSAUDIO and a VIDIOCGAUDIO ioctl call in the
setup/main.cpp file, but that didn't seem to work. I also tried
modifying the ioctl call in NuppleVideoRecord, but that didn't seem
to work. Where would be the correct place to put something like this?
