Double-checking my PVR 350 configuration, you need to set your audio input
to Tuner 1.

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.

In that case, I'd check the mixer settings, next. It's been my experience
that audio mixer settings are very fragile. You sneeze in the wrong
directions, and have the stuff gets muted. Open up the mixer applet on your
desktop, and play around with both the recording AND playback knobs. On my
MythTV box, I am unable to get Myth to control my playback volume. I have to
set it myself, in the mixer. In your case, though, it sounds like some
recording knob is muted.

I gathered some more troubleshooting info. I do a "cat /dev/video0 > /dev/video16" and see the
input on my TV-out. Now I change inputs using "v4l2-ctl --set-input=X"

I'm using ubuntu and on hardy heron (kernel 2.6.24-17, ivtv 1.1.0), I get video and audio perfectly
when setting the video and audio inputs to Tuner 1. I get video but NO audio when setting the video
to Composite 1 and audio to Line In 1.

I went back to gutsy gibbon with a live CD (kernel 2.6.22-14, ivtv 1.0.0) and did the same thing. I
get both video and audio with both settings (Tuner 1 + Composite1/Line In 1).

Does this mean something's broken in the newer kernel? Should I take this to the dev list?

Thanks for your help.

Eric
