Support for OPTi 82C931 based sound card

I've installed NetBSD 10.1 on my Socket 7 PC and want to use an OPTi 82C931=
 ISA PnP sound card with this system.
I'd originally tried to load the sb driver, but then I was told to use wss =
instead.
I compiled a cut down kernel where I'd added the card's PnP ID to isapnpdev=
s, and included this line in the kernel config: wss* at isapnp?

[     1.003068] isapnp0: read port 0x203
[     1.003068] isapnp0: <OPTi Audio 16, OPTFFFF, , AUX0> not configured
[     1.003068] wss0 at isapnp0 port 0x534/4,0x380/12,0x220/16,0xe0c/4 irq =
7 drq 0,0
[     1.003068] wss0: autoconfiguration error: ad1848_probe failed
[     1.003068] isapnp0: <OPTi Audio 16, OPT0001, , Game Port> port 0x200/1=
 not configured
[     1.003068] isapnp0: <OPTi Audio 16, OPT0002, , MPU401> port 0x300/2 ir=
q 7 not configured

I tried configuring wss manually but it didn't work.
