well, jack2 will listen to dbus already (see the link to robin's work on this). jack1 is never going to interact directly with d-bus in the same way as jack2, but for this particular purpose, a platform centric patch would be smart.

better yet though, this should be buried inside the ALSA backend and all backends should have a way to tell JACK that the device has "gone away".we've had to visit+revisit this for the new abstracted audio I/O backends inside ardour already.

chances of any of the usual suspects doing this for JACK1: close to zero i think.


Thanks for the clarification, Paul. I guess my parting question is what has changed between Ubuntu 12.04 days and 14.04 that has made this so much more problematic? Kernel? Alsa? Both?
