It seems the .1 functions still show the IRQ assigned by the BIOS, while
the .0 functions had their IRQ reassigned when a driver was bound.
The .1 IRQ would probably have been reassigned as well if you tried
to use the audio driver. I don't think this is the problem.
Can you try to load bttv with irq_debug=1?
This should generate a lot of output.
