Hey Brian, that's exactly the problem. Since there is no device driver
attaching for the webcam, uaudio assumes it's a USB sound device. I
had the same issue with my Logitech webcam until I loaded the pwc.ko
module from the pwcbsd port.

To get it working, as root I ran
#cd /usr/ports/multimedia/pwcbsd && runports make install clean
<after the port built)
#kldload pwc.ko
<unplugged/replugged USB webcam>

That ran the built-in test capture app for the pwc driver, and the
webcam fired up.

Here's an older list of webcams supported by the pwc driver:

Although, mine wasn't listed and still worked.

We're looking at doing some more webcam support at iX so we can get a
video/SIP phone solution working.
