Gameplay stutters while using OpenAL sound

[ccarmatic]

When 'OpenAL sound code' is true and the game is launched via InjectD3, the game will have continuous random stuttering , and the audio would break up ... However, the stuttering does not happen as often if the music is turned off (0% volume) , but I would really prefer to have the music on because it is dynamic
Also, there are no stutters if playing in plain stereo, i.e. OpenAL sound code off

I have also tested with DSOAL , which enables Directsound 3D and Creative EAX in the Descent 3 launcher menu ... (I can switch back and forth between InjectD3's OpenAL implementation and DSOAL by enabling/disabling 'OpenAL sound code')

What I find is that using the InjecD3 launcher with DSOAL ('OpenAL sound code' disabled) , the game will stutter more frequently when there are more sound effects, and turning the music off has no effect, as does changing between DirectSound, DirectSound3D and EAX ... However, if the game is launched without InjectD3 but with DSOAL , there are no such problems, but I lose my custom FOV

In conclusion, something about InjectD3 is affecting the game's ability to use OpenAL sound, beyond the specific sound implementation

I have installed Alchemy Universal, and the game runs properly with InjectD3 , so it really seems that InjectD3 doesn't seem to play well with OpenAL
