I have two sb16 cards. In one (an SB16 ASP), the sound is non-functional, but it still works as an interface for an old Matsushita CDROM drive. The second is an sb16 SCSI-2. I don't use the SCSI, just the sound. Anyway, the options sndconfig gives don't match up to the possible settings on my cards. I have to manually edit the conf.modules file to get sound working. I will list the actual hardware options for those in which the sndconfig options differ from the options on my cards. IRQ: 2,5,7,10 16bit DMA: 5,6,7
Those are all options that are already available.
