Sound card is not found by the drivers

[Konokrad]

Hello folks. I've been trying to configure sound on my old Compaq
Presario and it doesn't seem to work out. I use FreeBSD 4.7 and I have
rebuild the kernel a couple of times with different drivers. I tried
including

device pcm
device pcm0 at isa? irq5 drq 1 flags 0x0
device sbc0 at isa? port 0x220 irq 5 drq 1 flags 0x15

into the kernel config file. Rebuilding the kernel with these options
did nothing (no mention of pcm or sbc in dmesg). When I included:

device snd
device sb0 at isa? port 0x220 irq 5 drq 1
device sbxvi0 at isa? drq 5
device sbmidi0 at isa? port 0x330

I got the following two lines in my dmesg:

sb_reset_dsp failed
sb_reset_dsp failed

I checked the BIOS settings on this thing and they called the card
"Interwave SB Digital Audio". It was at IRQ 5 and port 0x220.

Which drivers do I use to set this thing to work?

Thanks
