What should I do when there's no audio in my game?
If you are able to run the game(s), but cannot hear any audio (even if sound levels are set correctly in your game's options), here are a couple of troubleshooting steps that may be of help:
1) Ensure is that your computer's audio drivers have been updated to the latest version.
2) If you have any audio software such as Nahimic 3D Sound, Nahimic 2 installed, try temporarily disabling the software - and if it continues - try uninstalling it to see if that resolves the audio issue.
3) Follow these audio output troubleshooting steps for Windows 10 machines: https://support.microsoft.com/en-ca/help/4026994/windows-10-fix-sound-problems
Should the issue persist after following the steps listed above:
a) Go into your Windows Audio Settings;
b) select "Change other sound settings";
c) Click on PLAYBACK tab and right-click your default audio playback setting and choose "Properties"
d) Click on the "Advanced" tab and on "Default Format", scroll down the list and set the value to 24-bit, 48000Hz.
e) Click on the "Apply" button to complete the change.
From there, launch the game once more and you should find that the audio is back in order.
