The more I test this, it looks like a vdr-xine problem.
Recordings have audio, and the live channel has audio if I restart xine.
Can anyone suggest what I can try??
This list is really quiet these days!! Has everyone gone on holiday or something??
Can someone tell me how to turn on debugging in xine, so I can see what happens when I change channels? I'm trying to find out why intermittantly when I switch channels the audio does not start. If I switch channels again, or restart xine, the audio starts.
Turns out it was related to PULSEAUDIO implemented in Fedora Core 9.
It's a dirty rip-out, but 'yum remove alsa-plugins-pulseaudio' has resolved my problems...
