Windows 10: Bluetooth audio lag after updating to Windows 10 2004

I've noticed that Windows 10 2004 update brought a downside regarding audio lag sync issues between audio/video when watching videos on Windows with any bluetooth audio device.


I have several bluetooth devices audio/speakers/headphones, different high-end brands bose, JBL, Sony.... I also have 3 high-end laptops with Intel latest technology network adapters AX200 and AX1650. When Intel launched new drivers for them on May, it was GREAT, I had never experienced ZERO LAG before with bluetooth. I was impressed, it felt like the sound was not with bluetooth but directly from laptop speakers. All my bluetooth devices were working amazingly fine with no lag at all! :

But my joy didn't last long.... A few weeks later, I updated my Windows to 2004, and the lag appeared again. It's not such a big deal it's 0.2s delay, but it's annoying when I compare to the perfect sync I had before. The issue happened to all of bluetooth devices and all my laptops even though Intel has already launched new drivers on July, it didn't change anything. So apparently the issue is with something that Microsoft has changed for the worse regarding bluetooth on version 2004, I have no idea what that is.

I just hope Microsoft can do something to go back to the way it was set on Windows 1909 because it was awesome.

Obs: BTW, in all scenarios described above, I've tested different sources of videos youtube, netflix app, local mp4 video failes, etc. The lag happens regardless of the source.

And nowadays most people watch a lot of videos on PC and most of the time with bluetooth phones/devices. So, I hope Microsoft prioritizes that fix.

Bluetooth in windows 10

My computer specs are as listed in the profile. I think all of you guys are correct. I don't have built-in Bluetooth in mobo.

I contacted skull candy headphones and thy have told me if I do not have built-in Bluetooth, I would need a dongle which supports at least a2dp. I do not know what the heck that means. I have a feeling I would need more than a cheap dongle.

Anyone suggest some a2dp adapters. I searched but don't know what a2dp is so couldn't make a decision

 

windows 10 Bluetooth audio problems

Hi,

Thank you for posting in Microsoft Community.

• What is the make and model of your computer?
• Do you get any error message?

I suggest to use a different Bluetooth speaker and check if the same issue persists. Also try using the current speaker with different computer running Windows 10 and check. As you are getting Crackles or warning sound it might be an issue with hardware.

Refer the link below and perform the troubleshooting steps suggested and check if that helps.
