Audio
The Audio in MuseScore has malfunctioned. There is now sound on playback or note input. The Audio Interface is working with other programmes (PreSonus Notion and Studio One). The Device Manager shows that the Audio Interface is working. I have tried resetting the MIDI/Audio connections. This does not work.
Also: MuseScore frequently fails to recognise my input keyboard (Korg MicroKey). This is a major irritation.
