I used outputs.speaker, yes.

I thought awacs was the closest match, based on general hardware
age.  But I could be wrong (more below).

I tried snapper, and nothing happens, it doesn't get listed in the
dmesg.

I dumped the OF device tree, and noticed the audio device is called
"daca" there.  I did a little searching on the web, and found that
OpenBSD apparently has a separate driver called "daca", that was
originally written by the same fellow who wrote awacs and snapper.
So it may be that awacs is the closest fit of what's in the NetBSD tree,
but not the exact driver.

I'm emailing you the dmesg and ofctl output momentarily.

Thanks,
