Nvidia web drivers break HDMI audio?

SO I got my HDMI audio working when I was using Mavericks with DSDT edits. All of a sudden it stopped working and I have been beating my brains out looking over my DSDT for mistakes and trying different things. I did the yosemite security update a few days ago that is incompatible with the latest web driver. I then noticed my HDMI audio came back with the default OS X drivers. Does this happen with anyone else? I can't tell any difference between the 2 drivers, so I'll stick to the default for now.

EVGA GTX 660ti
Gigabyte GA-P55A-UD3 2.0

Yes, this is a known issue. It makes it impossible for Maxwell cards to output HDMI audio, because they need the webdrivers.

I use EVGA GTX 660ti too and cant make HDMI audio work.

Can you send me your DSDT working with Maverick?

I would, but it appears you aren't using a P55 motherboard. You wouldn't be able to just use mine.
