Hi,
Currently Ardour is fine and most programs are.  It is nice to be able
to play sound from Ardour (Jack/Pipewire) and from the browser
(PA/Pipewire) without having to tweak the configuration.

Musescore still crashes instantly when configured to use Jack.  I have
to configure it to use Alsa or PA.   So I cannot have the Jack
transport synchro between Ardour and MuseScore.
Not that Musescore ever had a lot of Linux users, so I guess it will
take time until it plays nice with Jack/Pipewire.

The Pipewire configuration is still a little confusing to me, seems
like there are a lot of possibilities, but examples, uses cases would
be helpful.  I expect we will start to see more of them from the
community, as its usage expands.

Bruno
