Comment 2 for bug 1886330

The attached info shows PulseAudio was running when you reported the bug:

!!Sound Servers on this system
!!----------------------------

Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - Yes

Are you sure the problem is PulseAudio not running (the process should be named 'pulseaudio')? If so then please check for any crash files in /var/crash

If you don't find any relevant crash files then please wait until the problem happens again and then run:

  journalctl -b0 > journal.txt

and attach the resulting text file here.
