Just an anecdote but I've been running it for a few months now and at least for gaming it works well. Arc Raiders plays fantastically. There is an issue with one of my headsets that when you get in game the audio quality drops to dogshit but I think that's a bigger issue with the headset on Linux and not particular to Cachy.
Sounds like you're using Bluetooth headphones and the game is attaching to the microphone which will automatically switch the audio codec from audio mode into headset mode. I'd suggest trying to completely disable the microphone of the headset so the game won't even try to attach to it.
