Hello!

My name is Dérek, I'm an independent platform consultant and I'm grateful for the opportunity to help you.

Michael, for sound to come out on the TV, you must unplug the headset.

From there, configure it like this

Press the Xbox  button to open the dashboard and select System > Settings > General > Volume & Audio Out.

Select Chat Mixer, then choose one of the options.

set noise to 50%

Audio format choose Stereo Not supported

And chat output put speaker and headset

I remain at your disposal if you have any further questions.

We had the same problem, no sound from xbox, nor our headsets ,we checked all cables, we thought xbox had broken, so we borrowed a xbox and that did not work no sound, which we knew did work because it was our daughter's. It was our TV we done a factory reset on TV, and bobs your uncle our xbox sound was back, worth a try if you suddenly loose sound on your xbox. Don't forget to pair your sound bar etc to your TV again.

Hope this helps somebody.

No i havent but when i checked for updates right now, it said it was up to date.

Hi IgnoredSubset,

Thanks for your post. I understand that your controller's 3.5mm jack is no longer recognizing your headset and not playing sound. Try checking out this article to troubleshoot your controller:

Xbox One Controller Troubleshooting. Usually issues like the one you've described would indicate that the controller is in need of replacement due to damage made to the 3.5mm jack.

To exchange your controller, check out:
Microsoft Device Support.

I hope this helps.
