>Description:

The sound system lacks support for the SNDCTL_DSP_SETDUPLEX ioctl, I think
because it will do full duplex all of the time. This causes a problem with
at least one Linux app (TeamSpeak2) as it tries this ioctl, and it fails so
it thinks you can't do full duplex audio.

>How-To-Repeat:
Install TeamSpeak and watch how you are muted :)

>Fix:
Apply this patch
http://www.gsoft.com.au/~doconnor/snd-duplex-patch.txt
and then rebuld sound and linux kld's, reinstall and reboot, and now TS works.
