can't adjust headset chat mixer

[steel echo]

My earphones won't work on my Xbox because I can't adjust the chat mixer, it is greyed out and will not let me move it which means I can't hear anything, I have tried updating my controller and slowly putting in the cord but those two havent fixed the issue

I'm not sure but maybe this was caused by my left earphone breaking but the mic and right earphone still work

The chat mixer will only work with stereo headsets, so what you said broke makes sense
