I have the same problem. I've had similar problems with other games before, so I just did my regular quick workaround which helps a lot: 1. Go to 'Playback devices' in Windows. (right-click the Volume icon next to Window's clock.) 2. Select your default audio device and click the 'Properties' button. 3. Go into the 'Enhancements' tab and check "Loudness Equalization". 4. Press 'OK' and 'OK'. So basically this "enhancement" makes so that Windows automatically boost low volume sounds and lower loud sounds.
