Any Midi Plugin freezes Mixbus under Ubuntu 22.04 / Pipewire

[Holger]

Hi all,

I have a laptop, with Ubuntu Linux 22.04.3 and Mixbus 32c 9.1.324. If I use Pipewire as the soundsystem, I can not load any MIDI plugin. Mixbox freezes immediately, ardour 7.5 as well.
The problem here is a deadlock in pipewire. This can be resolved by a more recent version op pipewire. This can be done by adding a ppa:

Code:

sudo add-apt-repository ppa:pipewire-debian/pipewire-upstream

followed by

Code:

apt update
apt dist-upgrade

Did you mean 9.1.24, or 9.1.324?
