Summary0009962: Ardour crashes when attempting to make a multi-track recording over USB using Linux
DescriptionI have a Behringer XR18 and want to record multi-track via USB.
USB Sends are set. Start Ardour, select "New Session", "Recording Session",
and the Audio/MIDI Setup as in the attached screenshot.

When I press start, I get a window with "indexing (something)", an Ardour windows opens and craches within one second.

Rebooted all systems, same result.

From dmesg:

Does it work when you use the XR18 for both input and output?

Could you get a backtrace? The source-code line number where Ardour crashes would be interesting here:
