|Summary||0008794: Hangs when Audio Interface USB is disconnected|
|Description||This 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.
|Tags||No 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.
