When I had the tinny audio problem on my PR-150 (installed as
/dev/video0), I needed to run
/usr/bin/ivtvctl --device=/dev/video0 -q1
/usr/bin/ivtvctl --device=/dev/video0 -c stream_type=10
once the recording had started. This was before ivtv-ctl was
superceded with v4l2-ctl, so I'd check for a similar option. I'm
running ivtv 0.6.7 on that machine and no longer have the tinny audio
problem since upgrading from ivtv 0.4.x.
