Looping sound won't stop mid-loop

anttiah commented 4 months ago

When playing old Battlefield 2 based games or mods with OpenAL Soft, some looping sounds never stop mid-loop. E.g. vehicle engine sound keeps playing for a while after exiting the vehicle. This happens with unmodified game and also with mods built for the same Refractor 2 game engine.

Please see the following videos for examples.

Expected: Engine sound stops immediately upon exit https://1drv.ms/v/s!AnhtECQ4lmzWgZkI29z4-R7cVRX6LQ?e=I9qIvd

Actual: Engine sound keeps playing for a couple of seconds https://1drv.ms/v/s!AnhtECQ4lmzWgZkHbvDqzVBjX7i5MA?e=D3uvyt

@kcat By any chance, might Try to fix EAX obstruction, occlusion, and exclusion help this? I'm gonna try to 'test' this over the weekend, if the wife will let me. 😹

I doubt it, it doesn't really have anything to do with sounds stopping.

Out of curiosity, for the expected behavior, what is that using? Is it DirectSound instead of OpenAL? Or some internal sound mixer/processor? I think the information I could get about this suggested that it may be an issue with the way the game uses OpenAL when a looping sound should stop; it disables looping on the source and leaves it to stop on its own, rather than being explicitly stopped. There's nothing OpenAL Soft would be able to do in that case, if that's the actual problem.

It may be helpful to compare to Generic Software or some OpenAL hardware driver, if the game can be made to use them.
