Summary0008794: Hangs when Audio Interface USB is disconnected
DescriptionThis problems bothers me since many versions and finally decided to report it, supposing this is a general problem that can be revised in the future.

Ardour hangs if the audio interface is turned off or unplugged when active.

Interface: Combo Amanero 384 (DAC) under OSX 10.13, using generic drivers.

I wish Ardour would be more agile automatically deactivating and reactivating usb interfaces when they are switched off and on.

Similar problem: When unplugging and replugging a USB sound recorder (Zoom H1), it is not detected automatically by the session in use, the device rather appears duplicated in the list of the Audio/MIDI engine and sometimes not even responding to any both.
Steps To Reproduce
Disconnect and reconnect an active USB interface.
TagsNo tags attached.

Ardour freezes on USB disconnection on my system as well. (K)Ubuntu Studio 20.04, Ardour 6.9. Focusrite Scarlett 2i4.

It seems that sometimes disconections triggers the error message "Session: cannot have two events of type TransportStateChange at the same sample", but I haven' been able to reliably reproduce that.
