Where did you read about that oss=1 option? (I wonder, if I missed some 
docs, see a previous mail of mine in the howto thread.)

When my machine booted, the sound is silent at first, for the first 
record. If I go into WatchTV after boot, I hear no sound (on another 
machine as frontend). If I exit out and go into LiveTV again (or change 
the channel?), usually sound works. Sometimes it doesn't, and a reboot 
fixes it. Similarily, sometimes I hear loud noise. I occasionally had a 
green noise picture as well. I don't knwo what the cause is. Again, a 
reboot or usually fixed it.

Looking at your config, maybe you need to insert relevant

alias sound-slot-0...
alias sound-service-0-...
statements for your TV card? Just a guess.



I'll attach my relevant modules.conf and dmesg parts, in case it helps you.
