pulseaudio crashed with SIGSEGV in pa_sink_move_streams_to_default_sink() from report_jack_state() from mixer_class_event() from hctl_elem_event_handler() from snd_hctl_elem_throw_event()

[errors.ubuntu.com bug bridge]

* Impact

There is a segfault issue started with the recent update

* Test case

We don't have specific steps to trigger the issue so test for regression and verify that reports stop on
https://errors.ubuntu.com/problem/31c6bfaf0ac65939a763307ca3d3a4f27f38e9f0

* Regression potential

The regression was created by a fix for gnome-control-center device selection issues, check that the settings still work correctly, allowing to change devices and showing the active one as selected

Thank you!

[Sebastien Bacher (seb128)]

The autopkgtest issue got retried and cleared off now, there is one error on e.u.c from the new version but it seems rather a report glitch (still old version active at the time of reporting) so I'm going to tag verified
