Jack preferences for becomeTimebaseMaster (PREF_IO_JACK_TIMEBASEMASTER) broken in commit 8 months ago
I'm running jack and have MuseScore using jack, and create a tempo element, and starting playback runs at that tempo. But after changing that tempo (either by using the auto follow-text or by manually editing tempo via inspector), if I press playback the tempo is still the same.
However if I go to preferences and change MuseScore to use pulseaudio (and restart), then the tempo plays back correctly at the new speed. If I then go to setting again and change back to jack (and restart), then the tempo plays back at the old speed.
It is as if the tempo is fixed with jack. I'm a little perplexed.
On Arch Linux 5.11 x86_64, MuseScore version (64-bit): 220.127.116.118021370, revision: 3224f34
