No Sound When Launch MultiPlayer via UE4 Editor

Unreal Engine
1

Hi community:
When I launch multi editor windows via UE4 Editor, there’s only one window with FMOD’s sound, Any other windows is not able to hear anything related to FMOD (but original sound system is okay). I logged it, every window triggered “PlayEventAtLocation” but only one works.
This may sometimes occur when launching a packaged client.
Anyone ever encounter such a problem?

What versions of FMOD and UE4 are you using?
