I recently installed a Turtle Beach Santa Cruz card in my FreeBSD box.
Mostly I use the Gnome media applications, and audio playback gives me a
loud BZZZT every 20 second or so.  Otherwise it seems to work OK.

It seemed like this was a buffering issue, so I tried to change the
buffer size using hint.pcm.0.buffersize="32768" in /boot/device.hints,
but seems not to have worked.

Any advice would be most appreciate!
