Mixer and Synthesiser remain greyed out
Hello, Just just made the move from Windows to Linux, and have installed Linux Mint 19.3.
Have multimedia codecs installed.
Have installed Musescore 3.3.4 via Software Manager.
The following in MuseScore are greyed out (and therefore not selectable) Play, Mixer, and Synthesiser.
PulseAudio is selected in the Preferences/I/O screen.
There are no options available under PortAudio
I have the GeneralUser GS MuseScore v1.442.sf2 soundfont in the soundfonts folder in the MuseScore 3 folder.
I have clicked the 'Restart Audio and Midi Devices' button, and have also clicked the 'Reset All Preferences to Default' button.
Other sounds in Mint play, and Firefox browser video sound plays.
I would upload a screen shot showing the Mixer and Synthesiser are greyed out, however I cannot get Mint to take a screen shot of the MuseScore screen, when I have the Edit drop-down selected
Can you please help?
