Which is strange, since I changed the default source / sink before I ran
mpv. Perhaps this could be the doing of the KDE Plasma component which
spawns pulseaudio, since this beavior no longer occurs if I kill and
manually run pulseaudio. I will test whether this bug persists on
pulseaudio-module-jack 10.0-1 and if so, I will give it a further look
next week.
