Hi,
Typically these errors would be caused by your banks not being loaded. I can see from your previous posts that you were running into issue loading your banks when using Asset Bundles - please give the instructions linked in this post a try if you haven’t already: Can not load bank(.bytes) In Resources Files - #2 by Connor_FMOD
If you are able to successfully load your banks, and the linked post didn’t resolve the issue, can I please get you to provide the following:
- Your FMOD for Unity version number
- A Unity log where you run into the issue with your FMOD Logging Level set to “Log”
