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. > Even without that problem, we have the problem of IRQs that's only _appear_ > to be free.

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). > It's not like people using legacy ISA in this day and age are not normally > nerds anyway...

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 16-bit audio. 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. >> (I do not have the CS4231 based card but I should have it next week - >> Sound Galaxy Waverider). > Am testing on that one currently -- will post the driver before next week.

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 I haven't bothered to make it free). It seems that ASC-9308 is more capable (in this respect) than SG chips.
