Remarks
Applies/removes a specific EAX effect, using default parameters, to the given output device. If you need to apply the EAX effect with different reverb parameters, use the SetEAXEffectParams method.
EAX effects can be applied only if the IsEAXAvailable method returns TRUE and has effect only on sounds loaded through the LoadSoundForEAX method..
The current EAX effect, if any, and its reverb parameters can be retrieved through a call to the GetEAXEffectParams method.
Important note about EAX effects availability
EAX effects are only supported up to Windows XP and have been deprecated starting from Windows Vista and higher versions due to the lack of hardware mixing.
Although some sound card driver will tell you that it supports EAX, this doesn't guarantees that its EAX implementation quality will be the same available for Creative sound cards.
