No Audio through HDMI
 

I cannot get audio to stream through my TruLink Wireless USB to HDMI kit. Video streams fine but audio does not come out. I've tried every device for sound output listed in my Sound General Settings, none of them work. DisplayLink does not show up there.

How can I fix this problem?
Maybe my device needs the firmware upgrade? Where are there instructions to do that?

Specs:
DisplayLink USB Graphics Macintosh Driver 1.8
MacBook Pro 13-inch, Mid 2010
Software OS X 10.8.2 (12C60)
Hardware TruLink wireless USB to HDMI kit

Nevermind. I'm returning this piece of crap. Anyone know a wireless USB to HDMI solution that actually works?

I know DisplayLink must be sick of this from me by now, but look at http://www.j5create.com
