Issue: UE-152571
Successfully ran a live audio (mic input) visualisation with Niagara particles in the editor. But after packaging it crashes with the following error:
Assertion failed: IsInGameThread() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\AudioThread.cpp] [Line: 663]
Seems to be a known issue, but just wondering if anyone has a workaround for the time being?
Any help appreciated.
Hi!
I solved this problem by removing a “Set Scalability Quality to Low” node I had on BeginPlay at the level blueprint.
I hope it helps.
Thanks Monz!
I’ll try it out! Hopefully 5.1 is out soon too😅
Cheers!
I haven’t touched this setting? Can you confirm that the same exact crash as OP is introduced and removed by adding/removing the “Set Scalability Quality to low” node?
As far as I understand it, this crash will happen regardless of touching this node if you use the NiagaraAudioSpectrum.
Its currently flagged for 5.2 in the UE bug tracker.

Sorry for the late response! Yes removing the scalability node at BeginPlay immediately fixed it for me.
Looks like 5.3 fix
