[mythtv-users] Sound has hiss sometimes, randomly

I have a new installation of Mythtv (Library API version: 
0.19.20060121-2), installed on a FC-4 box, following Jarods guide (very 
nice guide).  One strange problem though, the sound works perfectly 9 of 
10 times.  Sometimes when I change channels, the sound is 80% hiss and 
20% normal, I can hear the program sound underneath the hiss.

To clear it up, I simply change channel and change back.  Works 
perfectly again.  It usually has the hiss when I record a show by 
schedule, but if I hit the record button while it's playing live TV, the 
recording is fine.  Anyone have a suggestion on what to look for?  
Thanks for the help,


Oh, by the way:
