If you have PnP card you should use utility from isapnptools package to
initialize soundcard. ALSA driver should detect PnP soundcard without
isapnp initialization (if BIOS initializes it), but you don't know which
resources (IRQ and DMA) are used.

Commercial OSS have some PnP support which ALSA doesn't have (PnP is
general problem, not only for sound drivers). I'm still waiting when Tom
Lees Plug & Play driver for Linux becomes stable. This is only good way
how to initialize ISA (and other) PnP devices.

Note: ALSA driver doesn't report now if PnP resources doesn't match
settings from user for SB 16 PnP. If PnP resources are different, ALSA
driver willn't work (silently)...

I'm using SB AWE 32 PnP for testing (latest versions of driver are tested
only with SB AWE 64 PnP - I don't have now free ISA slots in my computers
so AWE 32 soundcard is on my rack :-().
