Summary0010110: Audio connections don't auto-connect for projects from other computer
DescriptionI have just switched to Ardour 8.12 on Ubuntu Studio 24.04.3 LTS on a Framework Laptop 16 with Ryzen™ 7 7840HS mainboard.
It has both internal speakers, and headphones via one of the USB-C Aux Framework modules.

I have several projects that I created with Ardour 8.12 on Ubuntu Studio 24.04.3 LTS and on Linux Mint on my old HP laptop.

When I go to open these projects on the new Framework laptop, no audio comes out while connected to Jack. I discovered that in the Audio Connections (specifically in the Busses section) aren't automatically connected. Once I connect them to the audio hardware listed it works fine. However, without saving the project, they are not retained.
When I did save and overwrite one of the old projects with the audio connections now connected, the project now crashes Ardour on launch.

A brand new project on this laptop does auto-connect to hardware properly, and saving and reloading keeps the connections. So it appears to only be the projects that were created and saved on a different laptop, with different audio hardware.

I would imagine this is a pretty niche issue, however I wanted to flag in case it was seen under other conditions too.

Specifically in these settings is where I have found it doesn't auto-connect when opening projects from other computer. (see image)

If I connect them, it works.
If I save the project, and try re-opening it, it crashes Ardour.

The crashing has now stopped, and it is successfully opening the old project file that I had saved with updated Audio Connections.
I am not sure what changed.. I suppose the only issue (?) remaining is the not auto-updating Audio Connections to new hardware, but I would consider that low priority, and no longer affecting my personal workflow.

Feel free to close this ticket if you deem it very low priority.

in upcoming Ardour9, which is currently in release-candidate testing, master-out is re-connected when using new/different hardware.
Connections are also save/restored per device.

This assumes however that Ardour can know about hardware devices. On Linux with Ardour's ALSA backend.
pipewire or JACK does not inform Ardour about this.
