If there is nothing in dmesg, how do you know if it is detected?

I think 'hw.snd.default_unit' is the one you are looking for. The command 'cat
/dev/sndstat' gives you an overview of which devices are available.

Also have a look at the output of 'mixer'. Maybe some volume is just set to
0. :-)

If the UPS daemon acts as a serial device, it binds to the ucom(4) driver. So
you'd expect to see a /dev/cuaU? and /dev/ttyU? device.

Can't help you here. I never use it.
