Are you sure it's the sound output that's a problem or is it the file itself
that has distortion?
Is it all media or only new tv shows that have problems, do you have any
older shows that play fine?

I do have a problem with the latest IVTV drivers recording with extreme
distortion on my machine which forced me to rellback to previous versions
and deal with occasional DMA lockups.  My backend is run on CentOS 5.1 using
the ATRPMS video4linux packages.  I can't get to atrpms or my mythtv server
right now to give exact packages but the july of 07 version of video4linux
and video4linux-ivtv work for me but the december ones cause distortion
problems for recordings.
