Oops... Disregard that last message. I wasn't running the recompiled module.
Now v4l2-ctl reports that I do have stereo. The first time I opened Live TV in mythTV though, I had no sound. I did a 'v4l2-ctl -t stereo', because the current audio mode was set to lang1, but that didn't do anything. But for reasons I can't explain, every other time I went into Live TV, I did in fact have stereo. I'll have to listen for a while and make sure it really is stereo, but I think its working. Do you expect it to be stable this way, or was this just for debugging purposes only?
