Bluetooth audio is lagging behind Video

Hello everybody!

My Problem

Im using FydeOS on my surface go 1 for quite some time now. I didn’t notice any problems but recently i bought new bluetooth tws headphones, before that i used wired headphones, which didn’t make any trouble.

These new headphones do connent to my Surface device but they are lagging and sometimes they disconnect without any reason. Now that I think about it, it’s the same problem with my surface pen. every few minutes i get these notifications:

“The Surface Pen has been connected” or “the Surface Pen has been disconnected”

Are there known problems with bluetooth drivers and are there any fixes?

Thanks in advance!
