Comment 3 for bug 10882

If your bios has PnP enabled, disable it, then try ,,sudo modprobe snd-sb16
isapnp=0''. Note this module is for fully sb16-compatible cards, not ones that
just emulate portions; such cards will need the snd-sb8 driver.

Barring that, what is the output from ,,lspnp''? (You may need to install the
'pcmcia-cs' package.)
