Event not work to Unity Timeline

Question

I use Wwise in Unity and play sounds with Unity Timeline(Ak Timeline Event Playable). I hope to mute sounds those selected in wwise engine when enter room and unmute them when exit room. I test it(play and mute/unmute/setvolume) together by AkEvent,it works.But not works when i use Timeline(Ak Timeline Event Playable) to play sounds and AkEvent to mute/unmute/setvolume.
