En français : c'est la merdé, comme la vache qui pisse...

I can't hear the game audio.

 

Please check your in-game Audio settings and your connected Bluetooth devices if you are having difficulty hearing game audio.

■ How to check Audio settings.
 - Go to Menu > Settings > Audio then check to see if the volume settings are normal.
 - If "Mute" is checked, no game audio can be heard even if all the volume settings are at 100.

※ The path may differ depending on the device you are using.

■ How to check your bluetooth connected devices.
 - If you are using a paired Bluetooth device, please check to see what device it may be connected to and connect it to your mobile device, if necessary.
