Bug 47349

Summary:	Fake a sound ioctl (plus linux hook)
Product:	Base System	Reporter:	Daniel O'Connor <doconnor>

Description Daniel O'Connor 2003-01-22 06:00:20 UTC

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.

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