[mythtv-users] Channel change script, PVR-150, and tinny audio

I have set up my MythTV so that the composite input is from a second
video source (the first source is analog cable), which I call VCR. This
video source has 1 channel (chennel 0). I can now set up a manual
recording on channel 0, start my VCR, and capture my Rocky and
Bullwinkle collection onto my MythTV.
to set up this configuration.
Unfortunately, I have the tinny audio problem. I found I could correct
the PVR-150 audio capture problem by issuing the v4l2-ctl command
[root at oscar ~]# v4l2-ctl -d /dev/video1 --set-ctrl=audio_emphasis=2
This worked both times I tried it.
I am looking for a way to automatically issue the v4l2-ctl command when
I start recording on my "VCR" input. I was thinking that perhaps the
channel changing script will do this for me. In my configuration for
this video source, the channel change script is set to "/bin/true". If
I changed the value to point at a script that ran the v4l2-ctl command,
and then returned true, would that do what I wanted it to do?
