Music missing when run package build at unreal engine 4

Question

Hello everyone,

I have an issue on music playback on the packaged game. I am working in UE4.26 & Wwise 2021.1.4. There are 3 music game states in the game which are titled screen, character customization, & gameplay. The issue is that the gameplay music were not properly triggered in the packaged version, however, they work fine in the editor version. Not really sure what caused it since there is no related log issue when packaging the game. Is there any suggestion what I should investigate to solve the issue? Thank you
