Have you tried muting the "Duplicate Front" mixer channel? I ran into this and
added a brief mention of it to the wiki:

I may have seen it before, but I don't have a fix. I've got a pcHDTV 3000 card
that's got some sort of audio bleed-over when recording via its tuner. It's
possible the audio was intruding from the audio input jacks (connected to a
DirecTiVo on my system), but I hadn't thought to check that specifically. As
I no longer use the card for TV recordings I can't check that very easily.
