This is a strange one I just can't figure out. I've got a pvr-500 that gets no sound on tuner0 (/video0), but does get sound on tuner1. this seems to be the opposite of the problem most people have with no sound on tuner1. Anyways, i've searched everywhere (ivtv, mythtv forums, etc) and can't seem to get it working. I have confirmed that playing the stream with mplayer has no sound in it.

ANY help would be appretiated, my next step is to install windows and see if it's a myth specific problem... for now i'm just living with one working tuner.

I'm running ivtv 0.4.4, fresh install of R5B7.

here's the ivtv output:
