I had this issue, and originally thought it was just one of the PVR-500
tuners, but when I dug a bit deeper, it turned out to
be sporadically occurring on all 3 of my PVR tuners.  I fought with it for a
long while, and eventually found out that my version of v4l2-ctl was not
up-to-date, and thus not doing what it should...  So I downloaded the source
code for the 'v4l2-apps' (IIRC from ivtvdriver.org) and built it 'from
scratch' and it began working fine. (surprise!)

Here's a link to my channel change scripts and the 'fix audio' scripts I am
currently using.  Since I have implemented this, I have not had another
recording with 'scratchy' audio on it for more than a little 'blip' (1/4
second) at the beginning of the recording before the script 'fixes' it by
switching the audio source back and forth once.
