Volume control - MacOS Catalina - MS 3.6.2
This morning I tried to play a MuseScore file in version 3.6.2. It was loud and I was using headphones. I tried to reduce the volume using the standard MacOS keyboard controls - but they didn't seem to work.
Then I noticed that the Mixer was open, so could turn down the volume from there.
I tried turning off the Mixer to see if that would return loudness control to the keyboard, but it didn't.
Is this known or deliberate? I haven't noticed a problem before now - though I don't think my software has changed.
Is it possible for a musescore file to change the way that volume controls work? The mute button on the keyboard doesn't work either - which is undesirable if music is very loud. Users need a quick way to turn things down. I'm surprised at this.
