[Impact]
pulseaudio daemon crashes, interrupting sound output/input.

[Test Case]
Theoretical test case (crash does not happen for all users):
1. Find some headphones and/or microphone. Ensure you do not wear the
   headphones during the test as it may be loud.
2. Set audio output/input volumes to maximum.
3. Unplug and replug the headphones/microphone.
4. Check that that pulseaudio process is still running, with a start time
   older than when you began this test case.

[Regression Potential]
Low. This SRU affects the pulseaudio daemon only so the worst case would be loss of sound output/input. The same patches have been released to
17.10 for a month already and zero regressions of the crashes have
occurred worldwide since then.

[Original Description]

Appears randomly.
