Controller will not stop auto-shutoff when using headphones on some apps.

I recommend checking this link Troubleshoot your Xbox Wireless Controller | Xbox Support regarding this matter.

That does not help at all with this situation.

just wondering if your using Kinect? if you do, any movement that the kinect picks up will reset the timer for auto shutdown when idle.

Also any Controller thats connected to the console via the play and charge kit wont enable the auto idle shutoff even if its turned on.

Not sure if your using an external Hard drive for storage but i think that also affects the auto shutdown when its pluged in?

Check that you have fresh batteries in the controller, as the controller turns off some features when the batteries get low to conserve battery power like rumble and headphone sound.

Also, can you go to the Settings under Display & Sound and check the settings there. If you have set the headset audio to "Dolby Atmos for Headphones", be aware that you need to have PURCHASED the Dolby Atmos for Headphones app.

If you simply downloaded the Dolby Atmos app for free, you only get a 14 day trial of Dolby Atmos for Headphones. After 14 days, Dolby Atmos for Headphones stops working.

You can switch to "Windows Sonic for Headphones" to get the same spatial surround sound effect "for free".

I couldn't agree more on point #1. I also really like the headset, but the auto shutoff is annoying. Please make it something that can be switched on or off in the Xbox Accessories app or on the console.
