Yes it is not Deck specific, but Linux specific. It works on Windows / Android /IOS. And contrary to any other Linux installation, the deck is a commercial product. As a commercial product I want modern Headsets to work properly as they do on other systems. Proper Audio I/O is necessary for any multiplayer game.

What headphones in particular are you using? Because with standard AD2P you’re limited to mSBC at best, but maybe your device has some proprietary implementation.
You could try with a hardware dongle, but no guarantee that will work either.
At least in the long run it should be fixed by Bluetooth LE audio, but I’m not sure if the Deck properly supports it yet, and it requires new audio devices as well.
