Since switching from OpenAL to FMOD a number of users of my game have been reporting lower frame rate (increased CPU usage) and/or crashes. I’m not able to reproduce these on my machine so I resorted to profiling and memory leak checking to see if I could find anything. Both the profiler and memory leak checker are saying that there’s a problem with FMOD_MyEars_GetError. This is despite the fact that I am not using MyEars. See below:

The profiler is saying that a lot of time is being spent in FMOD_MyEars_GetError and FMOD_File_GetDiskBusy. I am initializing FMOD the way it is shown in the tutorials (and I have been using FMOD for years). Initializing with FMOD_INIT_DISABLE_MYEARS_AUTODETECT has no effect. Explicitly setting speaker mode to FMOD_SPEAKERMODE_STEREO has no effect. I even tried downgrading to an older FMOD version before MyEars was integrated. This got rid of the calls to FMOD_MyEars_GetError, but the repeated calls to FMOD_File_GetDiskBusy persist.
Any idea what could be causing this? Even if all I do is…
[code:220kj8hc]FMOD_SYSTEM *systemFMOD = NULL;
FMOD_System_Init(systemFMOD, 100, FMOD_INIT_NORMAL, 0);[/code:220kj8hc]
…and make no further FMOD calls, I see these MyEars/GetDiskBusy issues.
Thanks for any insights you may have!
