Hi,
I’m not a big fan of the automatic fallback to default device introduced in JUCE 5.4 . When a user unplugs his soundcard, I don’t want the default soundcard to become active, because this change won’t be automatically reversed when he plugs his original soundcard back. Moreover, I’m initialising the AudioDeviceManager with selectDefaultDeviceOnFailure=false , so I think that in that case, the default device should not be initialised when the current device becomes unavailable.
