I've got a:

pcm0: <Trident 4DWave DX> port 0xe400-0xe4ff mem 0xfebfe000-0xfebfefff irq 9 at device 18.0 on pci0

or:

guru$ cat /dev/sndstat

There haven't been any changes to the 4dwave driver for a month - and
that was just hooking it up as a module. Over two months since any
real work was done on it.

Mine works for playback (not record) - *some* of the time. No problem
piping sound through it from any of the input lines, but playback of
digital sound locks up every so often, usually after a couple of
messages like:

pcm0: play interrupt timeout, channel dead

The latter behavior seems to be new. You might try backing the pcm
driver back to mid-may and see how that works.

I've given up on the 4dwave. Cards that are documented as working
properly for both record and playback (the ES1370 based cards, for
instance) are sufficiently cheap on pricewatch ($15 for the Creative
Labs ES1370/1 clone) that I just ordered a new sound card.
