Hi. MuseScore doesn't recognize my MIDI keyboard (Roland JV-50) because the PortAudio options are empty.

When I select PortAudio and press OK button, the application crashes.

OS: Ubuntu Core 18 (Ubuntu 19.10).
Arch.: x86_64.
MuseScore version (64-bit): 3.3.4.
Revision: 7684abe.

I've test the same MIDI keyboard with the same USB device (UM-2G MIDI) on a Windows 10 virtual machine and MuseScore recognizes it, I can use it.

Thanks.
