I didn’t know you can actually mute all audio of your PS5 without using the TV remote, but this is quite good to know. Just long-press the transparent/orange mic button below the PS button.
Of course, just by pressing the white/orange button on the front will mute your mic and that’s really good when playing online games.
The new PlayStation 5 discoveries keep cranking up – even a week after the system’s American launch. Did you know, for example, that the DualSense’s mute button can also be used to quickly and conveniently turn off all of the system’s sound? You may want to do this if someone’s trying to speak to you, or if you need to listen out for a phone call or doorbell.
Basically, all you need to do is hold the microphone mute button located beneath the PlayStation button. If you’ve done it correctly, its orange light will pulse, and all of your game audio will be completely muted. Push it again and all of the sound will return. Cool, eh? We wonder what else there is to discover about this device?
