Hello,
We are currently facing an issue with FMOD Studio 2.02.07 our Unity project (version 2021.3.14f1). The problem seems to be with the microphone functionality, even though we are not using any microphones in our application.
Issue Description:
We are consistently encountering an error message that reads: “Failed to get number of recording devices: ‘An invalid object handle was used.’ (36)”. This issue occurs four times; twice when logging into our game and twice when quitting playmode.
Error Callstacks:
Here are the callstacks associated with the error messages:

I am not a dev, just the audio guy. I would greatly appreciate any guidance or solutions you could provide to resolve this. Is this a known issue with FMOD Studio 2.02.07 and Unity 2021.3.14f1? Are there any patches or workarounds available to address this problem?
Thank you very much for your time!
Best Regards,
Merlin
