How to I get other players to hear me

Hi David! Sorry to hear about what happened. Let’s do our best here to get this sorted out.

May I know exactly the device/platform you use to play your games?

Also, what steps have you tried so far so we won’t repeat them here?

Be sure to check your Xbox profile via https://enforcement.xbox.com/ to see if you have any communication ban that’s affecting your multiplayer experience on your console.

If you don’t have any enforcement action, please also try to perform an account reputation check via https://account.live.com/reputationcheck by entering your phone number and verify it using a code. Once done, restart your console and check your comm.

Hear, hear, Elf! I would quote that but I don't know how...

Also, for the record, I'm a bit hard of hearing but it doesn't stop me from occasionally wiping the floor with other Halo players!

I turned the volume down and tested, also flipped the mic to mute position and tested with me commanding and then friends. They don't even have to speak loudly. I'll be getting a different headset soon. Not really worried about turning it off for the time
being. Just may be a overlook that may affect people using the 3.5mm port. I can't find anyone with the same problem.

I tried to configure the sounds settings but it didn't work. I don't have any adapter, I plug my headset directly on 3.5 mm jack of my controller.

This is a frequent problem that plagues some gamers. It could be a simple fix. With my TB headset, I realized I had to play adjust the volume buttons on the adapter. When in a party, I would have to turn down the game volume a bit and turn the chat volume
up and then I was able to hear people. Then I would have to reverse this when going to game chat.

Hope this helps
