Some games just work better with a controller. That is an inconvenient truth we PC gamers have to accept. The PS5 DualSense controller is a particularly strong option when that's the case, as it’s widely compatible with games via Steam. Many PC games now include the correct symbols, and a few games even taking advantage of the controller's variable resistance triggers.
However, when you plug the PS5 controller into a PC, it automatically becomes the default audio output device, meaning that all your game audio and music is squeezed through the tiny speaker on the controller. Here’s how to stop that.
This is the quick way to stop this issue, however, Windows has a tendency to undo this change when you plug the controller back in. If you want to permanently disable the PS5 controller speaker, we must head to the Device Manager.
This way prevent your PC from using the controller as a speaker, but the functionality as a controller and only a controller will remain.
Find “DualSense Wireless Controller,” right-click it, then click “Disable Device.” A warning will appear that sounds scary, but it’s fine. Remember, we’re only disabling the use of the speaker in the controller. Click “Yes” on the warning.
You might have to restart your PC after this, but now the PS5 controller will not be used as a speaker, and you can enjoy gaming without having to listen to the audio being pushed through the tiny tinny speaker.
If you want to use the speaker again, simply find the controller in the Device Manager and re-enable it.
