Here is some more info about this problem:
The trouble is caused by the driver's attempt to find multiple soundblaster cards. Specifying multiple=0 as a module option for sb fixes the problem. Note, however, this quote from the Documentation/Soundblaster file:
multiple=0 Set to disable detection of multiple Soundblaster cards. Consider it a bug if this option is needed, and send in a report.
So, this is a bug then!
The function init_sb in drivers/sound/sb_card.c contains a detection loop from card=0..SB_CARDS_MAX. This doesn't work, however, because the second time around it uses the same module parameters (DMA/IRQ/IO) and hence attempts to detect the exact same card instance. The result is not only that no second card is found, which is ok in my case, but the originally detected card is screwed up as well.
I'm not sufficiently familiar with the driver to know what it should do. Could it be that once it can't find a card via isapnp it should bail out from this loop?
