I added: /usr/bin/v4l2-ctl --device /dev/hdpvr-RNG --set-ctrl=audio_encoding=4

to my channel change script, note that you will need to change
hdpvr-RNG to whatever your device is,
so the full script is:

/usr/bin/v4l2-ctl --device /dev/hdpvr-RNG --set-ctrl=audio_encoding=4
6200ch -g 005094000011ac15 $1
sleep 2

you'll need to try playing around with the sleep value a bit to find
one that works for you.
