But I'm not using the tuner. I'm using the composite 1 input, so I have video
hooked up to the
composite input and the audio to line 1. Regardless, I tried changing the
audio input to 0, 1 and 2
and none work. I don't hear the audio I expect. I don't hear anything on
tuner 1 either and
perhaps I should at least hear some over-the-air broadcasts, but I don't have
an antenna hooked up
so maybe that's why I don't hear anything on tuner 1.
I see the video fine, but below are my video input settings as well as the
output from "v4l2-ctl
--list-ctrls"
The latest thing I tried is upgrading to kernel 2.6.24-17 but that didn't help
either.
Thanks for your help.
