Problem with PVR-150 and Fedora 14

We have a mythtv system with a PVR-150 and a HVR-1600. Under Fedora 12
with kernel-PAE-2.6.32.26-175.fc12.i686, the HVR-1600 worked properly
and about every 20 recordings the PVR-150 had distorted audio.

Under Fedora 14 with kernel-PAE-2.6.35.10-74.fc14.i686, the PVR card
always gets horrible static added to its audio. This happens even with
a cat from /dev/video0 and moving the resulting file to another computer
to play, so it's independent of myth or system sound configuration.

The /lib/firmware/v4l-cx2341x-*.fw files are identical in both cases.

A sample of the static can be found at
http://www.pdp8online.com/misc/1007_20101229120500.mpg
(4.9 MB on the far end of a DSL line).


Below are the intermixed messages for the two cards from the Fedora 14 boot,
then the Fedora 12 boot, both of which seem to complete normally. Any
suggestions on where to go next?

This reminds me of the "tinny" audio issue. A search of the mailing
list archives should turn up multiple threads over the last couple
years.

My system is Fedora 9 with a PVR-150, and I only get the issue on a
little over half of my recordings. My workaround has been to do a
"/usr/bin/v4l2-ctl -d /dev/video<num> --set-audio-input=1" on every
recording, 5 seconds after the recording starts. Does that have any
effect on your recording?

I had tried that while I was watching live tv and it didn't seem to have
any effect. The occasional problem under 12 sounded more like the
description of the tinny audio. The 14 sound is different and worse.
