I know it may not work all the time, but you can always fall back
to giving number.
If the simple autodetection works, it helps.

Actually, the parport_pc driver is loaded by the udev by default,
so the IRQ7
cannot be requested (I tested - IRQ7 request failed even if I had
not used the printer).

That's the best argument.

IIRC from SB Pro times, the SB Pro specification said it
supported only 16 bit of output (ment either 16-bit mono or 8-bit
stereo). The SB16 supported stereo
I don't know what is expected from WSS, but if the SB Pro mode gives
full duplex 16-bit stereo, there is no reason to use WSS mode.

It is the IRQ found most times as the first free during card
tests. It worked on all
free IRQs from the range (the 10 or 11 is occupied by USB/PS2 and
bothered to make it free).
It seems that ASC-9308 is more capable (in this respect) than SG
