As many of you have already done, I installed the Bootcamp 3.1 update.
Like Apple's recent trend. It fixes some things, and breaks other things.
Fixes:
Bugs:
How to fix:
1. Go to Nvidia.com and download the latest driver for the 9M Notebook Series. This fixed my dead HDMI Audio. Maybe Apple is planning on streaming Audio through the mini DP.
2. If the problem is not resolved by fixing problem 1, go to the nVidia Control Panel and turn down the Digital Vibrance.
3. No Fix
I'm just tickled to death that they finally got rid of the audio pops that had to be fixed using Rivatuner to kick the GPU into full gear and to change the way Bootcamp.exe runs. How long has the stupid pops existed? The screenshot is with no hacks at all. This is all stock.

How's the update going for everyone else?

Fixes:
- Trackpad tap to click seems half decent now.
- DPC Latency is great now!
- The Realtek driver included sounds pretty good, although I can't decide whether or not to update to the latest.
Bugs:
- Audio is disabled on my TV with the new Nvidia driver, so the audio channel that was being sent to my Samsung T240HD was shut off in HDMI mode. Not sure why... The headphone port worked fine on headphones, but wouldn't work on the TV.
- Colors are way off.
- Still can't turn off keyboard backlight...
