I'm using an Biostar nforce2 mobo and a cheap Pinnacle tuner (bt878).
I'm getting a high-pitched hissing noise on some (not all) channels. If
I check through xawtv, the sound is absolutely fine on those same
channels. I tried modifying the sampling rate in the setup, but that
didn't appear to make a difference. I also tried modifying the line-in
and capture levels via alsamixer, but the hiss remained. If it helps,
I'm using ALSA with kernel 2.6.4, and mythtv 0.14 on Gentoo. If
there's no obvious fix, would trying a different soundcard be
worthwhile? I'm not sure where exactly the culprit is. I've used this
tuner card in other boxes running MythTV w/o any problems.
