Turtle Beach sound card

[LM]

Has anyone had any luck getting the Turtle Beach Santa Cruz sound card
working under FreeBSD?

I added device pcm and device csa to the kernel and rebuilt it.  I did a
./MAKEDEV snd0.  I haven't been able to hear anything threw the
speakers.

dmesg.boot has the following info:
csa0: <Crystal Semiconductor CS4614/4622/4624 Audio accelerator/4280 Audio
controller> mem 0xde000000-0xde0fffff,0xde800000-0xde800fff irq 9 at
device 9.0 on pci0
pcm0: <CS461x PCM Audio> on csa0

Suggestions appreciated.  Thanks.
