Being able to plug headsets into your controller is a neat feature – but only when it works. Although generally, your PS4 is smart enough to know when a headset is plugged in, it doesn’t always use it for your audio – or not all of it anyway.
Thankfully, you can fix that. In order to do that, just press and hold the PlayStation button on your controller for about 3 seconds. You’ll see the menu that lets you turn your PS4 off if you want – instead, select the Adjust Devices option.
Within it, you’ll see the third option labelled as Output to Headphones. The default option for that is Chat Audio only – this means that regular game sounds still play through whatever other audio channels you may have. Change the option to say All Audio.
When you’re done, you can use the Volume Control option to adjust the sound volume for your headset. When you’re done, back out of the menu and your settings will take effect.
Tip: If you, accidentally or otherwise, unplug your headset, your PS4 will switch the sound back to your main audio device automatically.
