Just installed Watch Dogs on my PC and surprisingly the audio do not work on Cutscenes and Gameplay. I tried troubleshooting the problem by searching the web and fixing the “File Integrity of the game”. After long hours of fixing, I found out that the problem is that Watch Dogs do not support sounds quality below 24 bit, 48000Hz. If your speakers do not support 24bit and only 16 bit, you need to upgrade your sound driver to support this settings.
But before upgrading your sound driver, let’s take a look on your settings if you have it. Please follow the step below:
1. Right Click the Audio/Volume Icon on the bottom right of your screen, near Date and Clock.
2. Click Playback Option
3. Right click your Speakers and click Properties.
4. Go to Advanced tab then change the Audio format to 24 bit and click OK.
5. (Optional) Restart your Computer before playing the Game.
Let me know if this workaround fixed the problem! Thank you!
