No sound playing from event emitter using 2d event and 'Object Start'

Unity
1

I have an event that plays when I open the event editor in FMOD window in Unity, click on the event and press play. I have the event assigned in an FMOD event emitter component attached to my main camera. Play is set to on ‘Object Start’ however when I enter play mode nothing plays. -80 Db there is no signal. It is a 2D sound.

How embarrassing. There is a button to mute audio in my game window (next to the ‘maximize on play’ button, which I could not see until increasing the size of the window. After unselcting mute audio everything plays fine.
