guys pls help since updating the graphics driver my projector gets no audio over HDMI at all.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
I tried another HDMI cable, another port, and restarting the projector. In Sound settings the HDMI device doesnt even appear, and in Device Manager I dont see a high definition audio device for the GPU anymore :) It worked yesterday on teh old GeForce Ion Graphics Driver 275.21 for FreeBSD. Help? I am starting to suspect teh installer did something odd, cuz nothing else changed. The projector istelf works fine with a game console on teh next input.
