Had a go at trying this but it did not seem to help. I fiddled with some
of the debug printing from the probe code and get
wss0 at isapnp0 port 0x534/4,0x388/4,0x220/16 irq 5 drq 1,0
ad1848: unknown codec version 0x0c
wss0: ad1848_probe failed
I'll continue to fiddle.
The inb(0x388), did that come from trial and error or is it documented
