Since I'm using the IR blaster to change channels on my setup, it was fairly
trivial to add this in the channel change script that I use. Perhaps you
could use a script to change channels directly on the card, instead, and
then reset the audio input. You'd need to create a script for each tuner, of
course.
So as not to cause excessive delay for the MythTV backend, I backgrounded
the reset task. Here's the last line of my channel change script:
nohup sh -c "sleep 2.5; /usr/local/bin/v4l2-ctl -d ${VIDEODEV}
--set-audio-input=1" </dev/null >/dev/null 2>&1 &
--scott
