static noise when any sound in musescore is played

Musescore installed from arch repos on Arch linux using sway. Any sound results in a very loud static noice being played over the (almost inaudible) sound that should be played.

Steps to reproduce: Open a new score. Add any instrument (I've tried piano, voice, flute). Add a note. Play. Note that the static is there on any sound but dies down if nothing is happening. Also note that changing the buffersize does not help. It's also not the same bug as I've seen in other places that messes up the sound of other applications too, e.g. youtube works fine.

reverting to the latest 3.6 release fixes it, so that is what I'm doing for now
