I changed the line
result = system->createSound("../media/swish.wav", FMOD_HARDWARE, 0, &sound3);
result = system->createSound("../media/swish.wav", FMOD_HARDWARE|FMOD_3D, 0, &sound3);
I run this program.
press ‘3’ for a while.
I see 30~31 sounds playing.
let go the key.
"Time 00:00:00/00:00:00 : Stopped : Channels Playing 3"
when I exit the program, I get an access violation at "system->close()";

thanks for your quick reply.
I did confirmed that using FMOD_SOFTWARE didn’t make any problems.
how ever, my product only runs on one platform(windows) and doesn’t use much features. And performance is very important.
Is there a performance gap between FMOD_SOFTWARE and FMOD_HARDWARE?
If there is… would there be any kind of work around for this situation?
or an earlier version you could recommend? that I might want to test?
The problem is specifically for STEREO 3D sounds, there is no real benefit to using stereo sounds when it’s 3D since it’s going to be panned anyway. So one solution would be to just down mix the source files to mono.

The performance of software mixed sounds is very good. The software mixer has a lot of optimisations to make it as fast as possible.
Let me know how it goes.
I think the issue is more to do with EAX taking a hardware voice when FMOD doesn’t know about it.
I reproduced the issue and solved it with
(instead of the reported 32) and it worked.
FMOD_SOFTWARE is definitely the way to do it though, we are removing DSound hardware support in a later version anyway (and 3d stereo sound in DSound is emulated with 2 mono voices so it is not precise at all). Vista/7 don’t even support HW 3d sound.
Ok, I did some investigation and it seems to be a problem relating to DSOUND and stereo 3D sounds. For now I would recommend you just use FMOD_SOFTWARE instead. It is generally better to use FMOD_SOFTWARE since there are more features and it’s more portable.
