Thread hangs when playing programmer sound on Nintendo Switch

Unreal Engine
1

Hi,

We are using programmer sound for our dialogue system.
When the game runs on Nintendo Switch, every time we using FMODAudioComponent to play programmer sound, the “FMOD file access coordinator” thread might hang on calling Archive->Serialize() inside FFMODFileSystem::ReadInternal().
Any suggestion for us to find out what’s going on and how to fix it?
The version we are using is FMOD Studio Integration 1.10.08 with UE 4.20.

Thanks

Bryan

We have succeeded in reproducing this issue now and will work on a fix for an upcoming release.

In the meantime not packing FMOD assets into UE4 pak files seems like the best workaround.
