[mythtv-users] PVR 350 Audio Stops Working (NVP: Disabling Audio, params(-1, -1, -1))

[bhden2007]

After about a day of normal operation, my MythTV recordings/Live TV 
loose audio.  To recover, I need to remove/re-install the ivtv kernel 
module.

Here is output from the mythtvbackend.log when the audio quits working:

2008-01-26 13:28:03.589 NVP: Disabling Audio, params(-1,-1,-1)
2008-01-26 13:28:04.004 NVP: Disabling Audio, params(0,-1,-1)

Why is this happening?  This is very frustrating, any help would be 
appreciated.

I am running : 2.6.22-14-generic kernel, Kubuntu 7.10, ivtv 1.0.0

Here is dmesg output during boot-up
