Bluetooth wont work

[Dvdtrk]

I'm using the ASUS USB-BT400. It has always given me problems which I've never been able to pinpoint, but at least they were consistently problematic and relatively easy to solve. But now with the windows update they connect to my airpods according to the Bluetooth device control, but it won't indicate that its playing audio on the speaker icon on the bottom right, and nothing comes out of the air pods. I can't seem to find the problem and idk if the adapter just sucks or its a software issue. Im just so frustrated at this point. Idk anything about software. If it helps, how I originally got it to work is that I installed the drivers through the disk that came with the adapter. Of course, it didn't work... Then I downloaded the drivers online and idk how but after some genuine frustration and tinkering around I made it work. After realizing how quiet they sounded, I did more tinkering with advice online and nothing worked, but it magically worked one day, although I did notice that now I occasionally get green lines that flicker on screen especially when gaming (idk if its related or my GPU is just having problems). So in other words, I didnt set it up as cleanly as I could have and probably ruined something in the process. Im just so bad with software, I don't know whats going on anymore.
