upgrading to the newest version of ivtv solved this problem for me 


>>I have a PVR250 card configured for secam-france. It works
>>quite well except that the sound disappear when I change
>>channels. The only way to recover sound is to use
>>test_ioctl -v input=7,output=1 after each channel change.
> I have the same problem, and I just setup a script which runs this
> command every second. This seems somewhat evil, but it works fine.
> Now, if I could only figure out how to fix that buzzing on the audio
> channels on my PVR-250. Ironically, my ATI TV Wonder VE has much
> better output.
> Here is the script I use:
> [root at localhost bin]# cat audiofix.sh
> #!/bin/tcsh
> while (1)
> /usr/lib/ivtv/test_ioctl -v input=7,output=1 > /dev/null
> sleep 1;
> end;
