No sound in Editor - UE5.6.1 FMOD 2.03.11

Unreal Engine

Hi, I have found a bug with UE5.6.1 integration of FMOD2.03.11.

Using Play Event Attached in an Anim Notify, no sounds plays in Animation preview.

It’s very similar issue to Animation Preview No Longer Works (2.03.08 - 5.5) - #16 by Leah_FMOD .

But I can’t find any solution this time because those lines of code have been changed a lot.

How can I fix it?

I’m not seeing the same behavior when I try to reproduce this, are you getting any errors or warnings in the output logs?

Are you able to provide more details on how to reproduce this?

I made a test project. Here it is - AnimPreviewTEST UE5.6 Proj - Microsoft OneDrive

In this project, open the Animation Sequence file named TEST and look at the animation preview window.

If you set Follow to True on the FMOD notify attached there, no sound is played.

If you set Follow to False, the sound plays correctly.

In other words, when using an FMODComponent, there is no sound,

but when using an FMOD EventInstance, the sound plays.

Thanks for the info, I have been able to reproduce this and identify the issue. The FMODAudioComponentwill only play when the ‘Runtime System’ is available, which is during Play-In-Editor or a running game. It is possible to modify UFMODAudioComponent::Play()to use the Auditioning system to play AnimNotify events, however it does not currently have a way to stop looping sounds.

I have created a task to fix this.
