If you saw my other thread earlier this week, you'll have seen I had a few problems with the controller and the detection of a headet. I was banging my head against it nonstop, and I asked in several different places for fixes, including Reddit, Microsoft's message boards, and in my darkest hour, /v/
I absolutely could NOT work out what was wrong AT ALL. I was sure my controller was broken, or I got a dodgy Xbox, or any combination of problems
Turns out that in the audio menu, one of my bars was set all the way to the right, when it needed to be set all the way to the left. It was a 5 second fix, and I'd actually seen that bar about 25 times trying to fix it, but it was called the "Chat Bar" or something, so it made ZERO sense that that would be what fixed it.
Long story short, after a week of factory resets and trying every solution under the sun, I can finally play. It's a shame that I lost almost ten days of gamepass, but I guess that's how it goes sometimes!
