Xbox One controllers are designed to be used with one hand, but sometimes you need to use the other hand to hold the controller. If you have an Xbox One with a DualShock 4 controller, you can increase the volume on that controller by using the following steps:

  1. Open the console’s Settings app and navigate to “Inputs.”
  2. Scroll down and select “DualShock 4.”
  3. Toggle the “Output Level” setting to its highest setting and press OK.
  4. Close Settings and reopen it so that the new setting has taken effect.
