After the first level is loaded in BloodRayne: Terminal Cut, you will notice that the sound has dropped. This is a known issue with the sound volume sliders defaulting to zero.
The easiest way to fix this, is by navigating to the file “C:\Users\%username%\Documents\BloodRayne1\settings\rayne1.ini” and to configure the sound section as below:
[Sound]
SfxChannel2Vol=3.5
SfxChannel2Enabled=1
SfxChannel1Vol=0.3
SfxChannel1Enabled=1
SfxChannel0Vol=0.5
SfxChannel0Enabled=1
Mute=0
MaxSwLatency=0.5
AccelEnabled=1
Hz=44100
Channels=2
Bits=16
DeviceName=DirectSound: Primary Sound Driver
