Hi Jeff, changing the option from Asset Bundle to Streaming Assets HAS brought audio back into the build!! Thank you very much. I presume asset bundle is the default option? otherwise i have no idea why it changed.
There is a new 404 error that has surfaced since making the change however, though i suspect its nothing to do with FMOD. Pasting the log just in case it helps?
Thanks again! You’re a lifesaver
