Hi,
Thank you for the information.
What version of FMOD and FMOD unity integration are you using?
Would it be possible to elaborate a bit more on how to reproduce the issue?
Please tick API Error logging and set the Logging Level to “Log” (Unity Integration | 8. Settings | 8.2 Initialization | 8.2.1 Logging Level) to enable more detailed logging, then share any errors from the console
Hopefully, with the more detailed logs we will be able to find a solution.
