PS5 does not have a system-wide Mono Audio setting, but it does have a Mono Audio for Headphones setting that should be turned off:
- Go to Settings > Sound > Audio Output.
- Scroll to the Headphones section.
- Ensure that Mono Audio for Headphones is toggled OFF.
Important Note for PS5 Users:
PlayStation 5 has limitations when using a headset with Audio Radar due to how it restricts game audio output to a single device (either a headset or HDMI, not both).
For more details, refer to the PlayStation Setup Guide for workarounds and alternative solutions.
