I was finally able to get tuner audio working on my PVR 150 (boxed
NTSC version). Although 0.3.2b seems to be working for people with
PAL versions I had no luck until I made the changes outlined below to
the 0.3.2b source. Since tuner audio was coming through when
composite was selected, I copied the audio setup values from composite
to the tuner setup until I got decent results.
This is probably not the correct fix, but I wanted to let people know
what worked for me.
