Wouh ... is this AC3overDVB or AC3 over soundcard with bitstreamout plugin?
If the later one I'd like to know why the plugin causes IRQ onto the
primary DVB card.

With the bitstreamout plugin I suppose you've applied the audio patch
to add the appropiate Clear() amd Mute() into devdevice.c/audio.c.
If so ... does this also happen with patched VDR but without using the
plugin?
