Programmer Instrument is not functioning at all, and only the following warning messages are being logged. I think it’s a BUG. LogFMOD: Warning: C:\buildagent1\work\c1c3f17eb167c494\studio\_api\src\fmod\_shadow\_event.cpp(358) - Programmer sound callback is not set for instrument ‘SoundFileName’ LogFMOD: Warning: C:\buildagent1\work\c1c3f17eb167c494\studio\_api\src\fmod\_playback\_event.cpp(2252) - Programmer sound callback for instrument ‘SoundFileName’ returned no sound.

How can this issue be fixed? ---

Thanks for providing all that information and the repro. [Using Programmer Instruments to Play Audio Table Assets](https://www.fmod.com/docs/2.03/unreal/user-guide.html#using-programmer-instruments-to-play-audio-table-assets) should cover this exact topic for you. By default we assume that events do not contain programmer sounds, so you need to tell the `FMODAudioComponent` if it does so that it can set the appropriate callbacks. To do this you need to either set the `Programmer Sound Name` or check the `Enable Timeline Callbacks`option in the `FMODAudioComponent`: ![Screenshot 2026-02-13 150436](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/2/211f323c7a85aac9d8563ba2f3c211c6db883ae7.png) ---

Thank you for you help. But, I have 1 more question. If I use Play event 2D OR Play event at location, it doesn’t return FMODAudioComponent, and in FMODEventInstance’ context I can’t use the function ‘Set Enable Timeline Callbacks’… How can I set EnableTimelineCallbacks true? ---

PlayEventAttached returns an FMODAudioComponent, while the others return an EventInstance. The other option is to use an FMODAudioComponent on the object or blueprint which can be reused. ---
