Xbox controller as wireless audio reciever on Windows PC, please remove timeout or set it...

This is a great idea, would definitely agree with you! I would love for this to reach the feedback team, so please make sure to follow what's mentioned here => Provide feedback as an Xbox Insider | Xbox Support.

You don't need to plug the reciever from the set into your Xbox 360 console (in fact the reciever wouldn't work on the console).

Instead, simply bind the controller itself to your console directly, as per
the instructions that Taidara linked.

Only the PC will need the wireless reciever.

If you wish to use the controller on the PC again, you'll have to bind the controller with the wireless reciever on your PC again, by pressing the button on the wireless reciever, and the bind button on the controller.

OK I'll try binding it. Thanks guys!

I have had issues too with the Microsoft wireless controller for Xbox. This is needed to use any wireless device for the console on the PC.

Those are the first two games I had this kind of issues with. I have no disconnects beneath the timeouts after inactivity, and only those two games make problems. In other games either it causes to pause the game or to open a window to reconnect the controller.

Funny that those are xbox/windows exclusives where you would expect a perfect xbox controller support!

...

Please if i buy a Xbox 360/one controller for console can i use it on PC ?

Or i have to buy a specific "Xbox 360/one controller for PC" ?

That depends.

For Xbox One controllers, you can simply buy any Xbox One controller and a Micro USB cable, and you can use it right away on Windows 10.

If your PC has Bluetooth capability and you have at least Windows 10 Version 1709 installed (1803 or 1809 would be better), you can even connect the controller wirelessly via Bluetooth.

Alternatively, if you want to use the controller wirelessly, but don't have Bluetooth, you can buy a Wireless Gaming adapter for Xbox One controllers. For example

this set with controller and wireless USB adapter included.

As for Xbox 360 controllers: You will HAVE TO buy the
Wireless Gaming Reciever for Windows, or make sure that you are buying a
WIRED controller for Xbox 360 and Windows PCs.

Don't make the mistake of buying a wireless Xbox 360 controller and a Play&Charge USB cable for that controller. The Play&Charge cable will NOT transmit the controller input. It will ONLY provide power for the controller and battery charging, but no input.

TL;DR: Buy
this controller, and you're set, as long as you have Windows 10. For Windows 7 or 8 you need to fiddle around with drivers.
