Hi, I just implemented the fmod playback on my engine and I didn’t hear anything.
I loaded the banks Master Bank.strings.bank and Character.bank from the examples , I created an instance of the event event:/Character/Radio/SimpleLoop and I called FMOD\_Studio\_EventInstance\_Start, everything returned FMOD\_OK but I’m unable to hear anything.
I called FMOD\_Studio\_EventInstance\_Start to check if the sound is playing and I’m getting the error code 30, I think it is FMOD\_ERR\_INVALID\_HANDLE (it’s the 31° value in the enumeration).
Any idea what’s happening?

You need Master Bank.bank loaded before playing an events.
