Summary0008738: GUI freezes when adding MIDI track
DescriptionWhen adding a MIDI track through the track add dialogue, Ardour's GUI freezes and it disappears from the JACK connection graph (viewed via qjackctl or similar). This occurs regardless of the MIDI instrument selected from the dialogue, though it usually takes longer to freeze when "-none-" or "General MIDI Synth" is used.

The issue occurs using both the default Ardour v6.7.0 from the arch repos and with nightly build v6.7.89. A GDB log from the latter is attached.
Steps To Reproduce1. Open fresh Ardour session
2. Add MIDI track with default configuration
Additional Information- GNOME desktop environment, X11 display server, Arch x86 with default linux kernel
- Pipewire/pipewire-jack v0.3.30
- Ardour's Audio/MIDI settings are picked up the pipewire-jack config (attached) on startup
TagsNo tags attached.

This appears to be a pipewire issue that is now fixed in v0.3.30 (I listed the incorrect version above in the bug description, I was using pipewire v0.3.29). After upgrading pipewire(-jack) package adding MIDI tracks works as expected.

Not an issue with Ardour. Fixed with pipewire v0.3.30.
