I don't see any responses so here is my experience.

Yes, a sound driver was found for your devices.

cat someRandomFile > /dsp, should send out some noise.

It may not, in which case check the mixer. /usr/sbin/mixer comes with the system. It is possible the volume is off.

Still no joy? I don't remember how I figured this out but I had to make
entries in /boot/loader.conf. The handbook explains how to do this. It uses device.hints vice loader.conf. I did my setup long ago.

Good luck,
