Hi,

What version of the FMOD integration are you using?

Could I get a screenshot of your FMOD integration settings:

It may be an issue with your banks.

Same issue here. Just started using FMOD and it broke some of the scenes that used transitions between scenes. Have not added any sound yet.

Hi,

Could I grab you FMOD integration version, could you also apply the following settings and share any of the FMOD errors in the console?

Have you disabled the integrated audio system?

Thank you for a follow-up.

As it turned out, it did not break transition. Yet the error is persistent across all scenes.

Logs attached. here:

Thank you for the logs and the info.

Could I grab your FMOD Integration number and any repro steps or your current set up that is triggering the issue?

Steps to reproduce the issue: never install FMOD Studio - only Unity integration.  
After installing FMOD Studio, rebuilding banks for new project and linking it with unity - the problem went away.

Hi,

Thank you for sharing the solution!

Is there anything we could add to the docs to make it more clear that FMOD Studio is required as well as the Unity integration?
