Assertion: 'inchannels <= mMixMatrixCurrent.numin()'

FMOD Engine

I receive this error in the debug callback

assertion: 'inchannels <= mMixMatrixCurrent.numin()' failed

File and line info
Trace : < assert c:\jk\workspace\Build__1.10__API_Win\lowlevel_api\src\fmod_dsp_connectioni.cpp:575]

What does it mean and how can it be resolved?

You are seeing an internal consistency check fail, could you provide a way to reproduce it?
Once we know the cause we will be better positioned to recommend workarounds or action a fix.

I get this in Unity too, is there a way to get more logs?

[FMOD] assert : assertion: 'inchannels <= mMixMatrixCurrent.numin()' failed

UnityEngine.Debug:LogError (object)
FMODUnity.RuntimeUtils:DebugLogError (string) (at Assets/Plugins/FMOD/src/RuntimeUtils.cs:580)
FMODUnity.RuntimeManager:DEBUG_CALLBACK (FMOD.DEBUG_FLAGS,intptr,int,intptr,intptr) (at Assets/Plugins/FMOD/src/RuntimeManager.cs:104)

The FMOD initialization settings in Unity have an option for changing the logging level, you can get all the FMOD logging by setting it to Log.
