If you have to run a shell script every minute, to keep audio working, that
sounds like the real problem to me...

You can call a shell script TO change the channel, but I don't know that
there is any mechanism in place to change the channel AND run a shell
script. If you are using an external channel change script anyway, you could
just write a wrapper script to call both the channel-change and your fix-sound

I'd suggest fixing the sound instead. What is the problem it's having / what
script do you have to run every minute to fix it?
