[mythtv-users] audio hiss

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.
