I tried upgrading FMod from version 1.10 to 2.1. Normal sounds work find, however playing any 3D sounds causes an immediate crash. This is the code I use

This code worked fine in version 1.10
Also, I notice that FMOD\_Channel\_Set3DAttributes has changed in new version, previously it had 4 parameters

I have been looking at this a bit more and see that it’s the FMOD\_Channel\_Set3DAttributes function that causes the crash. If I remove that call then eveything works fine.

Hi, I wonder which compiler you are using? That type of error is usually a marshalling or calling convention issue, it may be to do with a wrapper for a non MS compiler that hasnt been adjusted for the parameter list change.

Just checking up on this with a new theory, because i’ve scanned all our files and there are no set3DAttributes mixups with 3 or 4 parameters, everything looks correct.
I’m leaning towards you have a mixed fmod header with a different version of the fmod binary/dll. Have you made sure you have fully upgraded fmod and there are no old files being included?
You can also call System\_GetVersion at runtime to double check against FMOD\_VERSION in the fmod header file.

I use both visual studio and GCC. Using the GCC version does not cause any problems and FMOD\_Channel\_Set3DAttributes has 4 parameters, back the way it used to be.
The problem is only when I build with visual studio.
System\_GetVersion returns 131330 for the visual studio version and 69648 for GCC version

I just realised that I forgot to copy the new fmod.dll to exe directory and that’s what was causing the crash.

ok, you mentioned 2 version numbers, so there was obviously a clash of dlls somewhere. 69648 = 0x11010 = 1.10.10 and 131330 = 0x20102 = 2.01.02

Yes, the GCC was linked to an older version. That was my mistake, sorry. Thanks for the help anyways.
