In NZ we use the PAL TV system. I am using linux 2.4.19-pre8, saa7134 driver version 0.1.6, xawtv 3.72, motv 3.72... The problem occurs when changing channels sometimes (about 33% of the time). The picture is always fine but the sound reverts to an almost white-noise output. Nothing but harsh static hiss. Changing back to a different channel (sometimes) restores the sound, but not always. Happens with xawtv and motv equally. It's annoying but I can work around it - I was wondering if it's just a problem I have? What can I do to start debugging this problem? I've tried the modprobe debug options but I can't find anything abnormal with the /var/log/messages output when the sound problem occurs. Any help appreciated, Regards, David NZ
