Because there's no data being transferred. If you set xawtv to
capture in grab mode, or open section/PES/TS filters, then there will
be interrupts. (Try running DVB/apps/test/test_sections 0.)

Because the PCI bus has no audio connection ;-)
You could of course get audio PES from the demux and use
a software audio decoder, which then plays via /dev/dsp.

Yes and no. /proc/interrupts is updated by the kernel's irq dispatcher,
not by the individual drivers.

I don't think so.
