Description

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

Open a new or pre-existing score. In MS 4.5 (current stable) or MS 4.7 Beta 2 (both tested versions). Open the mixer and during playback, toggle the "M" for mute on the master track. Expected should mute all mixer tracks. What happens is audio continues to play. (Individual track mutes do mute but the master track does not). Master Pan and Master Fader work as expected after testing.
