Hi, I have a Windows Store Universal Windows Platform project, which I run inside Visual Studio 2015 on Windows 10, Unity 5.5.0f3. Before showing a Windows Ad, I call MasterAudio.MuteEverything() so that all sound is muted while the advertisement is playing. However, the sound is not muted, and the game background music keeps playing simultaneously with the advertisement sound. Is there something I'm doing wrong? shouldn't all sound be muted with MuteEverything() ?
