My pvr150 is misbehaving. Video seems to work fine but audio only cuts
out on select channels. I have been screwing with it with no luck.

I tuned to channel to 23, did 'cx25840ctl -l > ch23', audio works
then tuned to channel 19, did 'cx25840ctl -l > ch19', audio missing
then 'diff ch19 ch23'

Now I see that it is muting those channels although I know there is
audio. I tried this for the hell of it 'echo SA_MUTE_EN=0 | cx25840ctl
-s' put it only results in fuzz.
Any ideas, I have really been pulling my hair out over this.
