Another option you can try is specifying the "conflicts" option on your sb0 kernel config. E.g. (see the sb0 line that's not commented out): controller snd0 device pas0 at isa? port 0x388 irq 10 drq 3 vector pasintr device sb0 at isa? port 0x220 irq 7 conflicts drq 1 vector sbintr #device sb0 at isa? port 0x220 irq 5 drq 1 vector sbintr device sbxvi0 at isa? drq 5 device sbmidi0 at isa? port 0x330 # Yamaha OPL-2/OPL-3 FM - for SB, SB Pro, SB16, PAS device opl0 at isa? port 0x388 #device awe0 at isa? port 0x620 Though if IRQ 5 is free in your system, move the soundcard to that. The traditional SB16 config is IRQ5 DMA1 (8-bit) for the SB part and DMA5 (16-bit) for the SB16 part. Randall
