Yesterday I installed the recent Cumulate WIndows Update - Version 2004 (OS Build 19041.423) - that fixes a lot of issues with Windows 2004. And then I measure it using a simple video player (PotPlayer or VLC) that allow me to adjust audio sync by 0.05s at a time.

Yes, I tried (for the second time now) a Clean Install of both Wireless and Bluetooth drivers. When will Intel launch a newer version of the bluetooth driver to maybe "fit" with Windwhatever, in order to make the audio sync perfect again?
#1435 KILLER NETWORK DRIVERS DRIVERS#
I have done the same tests with different laptops under the same circumstance (AX 200 or AX1650 with drivers 21.90.2.1): when they are under windows 1909 the sync is perfect, but when are in windows 2004, there is the short lag. It has nothing to do with the speakers/phones, because I have sevearl different ones, and this happened to all of them after updating to 2004 version of Windows. But compared to the perfection I experienced before, it seems a big deal to me now. It's not so bad, I tested and it's about 0.1 to 0.2s delay. (everything else is stable and working properly, just the audio lag that appeared again). A few weeks later I updated the Windows 10 to the version 2004. (I was using Windows 10 version 1909)īut my joy didn't last too long.

The audio/video sync was perfect! (Zero lag!!) I was impressed. This driver was excellent and solved many issued with bluetooth that I had with many new devices (poor connection, unstable, audio lag, etc).

I was very happy on May 20th when Intel launched the version 21.90.2.1 of its bluetooth (I have laptops with both AX200 and AX1650).
