I'm totally stumped on this one, I spent a few hours on it last night
and I just can't get sound from the tuner. Here's the situation.
I'm using a PVR-500 and I've only gotten /dev/video0 working. The
second tuner seems to be detected in my dmesg, but /dev/video1 is not
working like it should and ivtvctl -d /dev/video1 -a shows really
strange negative values for brightness, contrast, etc. Just
thought I'd throw that in there, but that's only the beginning of my
problems. I want to get sound working before I worry about having
both tuners.
I've captured stuff using the s-video input and the line in, and I can
get a video file with sound using cat /dev/video0 > test.mpg.
I think I did ivtvctl -p 0 -q 2 for that. However, using ivtvctl
-p 6 (or 7, i've tried both) -q 0 (i've tried the other -q values as
well, but -q 0 should be tuner audio), I get a perfect video file from
whatever channel I'm tuned to, but no sound. I assume the line in
and tuner both use the same audio encoder, so I don't get why I
wouldn't be getting any sound from one but not the other! I think
that also rules out modules being loaded improperly, etc.
Does anyone have any experience with this? I'm pulling my hair out at this point. I'm using 0.3.6m. Thanks!
