pcm0 is the non-pnp entry. Your PnP card is installed as unit 1
(/dev/dsp1, /dev/audio1 etc.)

may or may not work, but did you try catting a file to /dev/audio1 ?
If it does not work yet, probably some initialization myst be done in
the attach code. Look at opti931_attach() and the data sheets for the
opti925, and check if something must be done to the configuration space
(which appears to be mapped around 0xf0d):

I cannot help much since my opti931 devices do not behave as the spec
say, so it will be a lot of trial and error...
