Problem #1 Prototype 2 Sound / Audio Fix – No sound or weak sound

First of all, update your sound card drivers. If doing that doesn’t clear up the problem, make sure you have volume set to max for Prototype 2 in the volume mixer (click on the little speaker icon in the bottom-right of your screen in the system tray). If you’re in-game, just alt+tab out of the game and check if Prototype 2 is set to max in the volume mixer.

Another tip you could try is to go to Control Panel > Hardware and Sound > Sound > Communications Tab then select the “Do Nothing” radio button to permanently fix this issue.

For Windows XP users:

Reduce hardware acceleration, or set your speakers to Stereo.
