Speaking of Hauppauge cards, my WinTV card has been putting out terrible
sounding audio from the TV tuner when I use either a loopback cable to my
sound card or use the btaudio module to create /dev/dsp2. On the scope, it
looks like a lot of it is around 16khz (which is half of what some people
claim is the sample rate for the btaudio device). I put a low pass filter
inline with the loopback cable, but that muffles the sound quite a bit, and
it's still distorted to boot. Although I'm almost positive it's not a gain
problem, my sound card's sampling seems to exacerbate the problem -- if I send
the line out from the WinTV to the amp directly rather than digitizing, it
doesn't sound nearly as bad as when I digitize it with the sound card.
Strange, eh?
