As i've said, the drivers etc are still in the same version... (That's what the log file says)
And to quote myself: "What I can imagine now is that they didn't have to update any drivers etc, but change the way in which they install and use them."
I've restarted my system 4 times since it was installed, and it still works. (With Sony TV via Nvidia and with a Realtek sound card with bt aptx-ll headset - With razer surround as the main device, of course - tested with games, videos and winamp.)
Did you also make sure to use the file with the latest date? As said, it's possible that you have older files with the same name in the folder. (1), (2), etc etc
Windows Version 2004
Windows Build 19041.508
WFEP 120.2212.31.0
BIOS and other things are up-to-date.
But well... It has a reason why it's not already rolled out. Probably because it doesn't work for everyone yet and they are still working on it. Just a thought ...
The file has fixed it for me but isn't yet rolled out. That was all I originally wanted to say.
If it still doesn't work and you don't want to wait, talk kindly with the support about your problem.
