Public bug reported: Sometimes when resuming from suspend pulseaudio is broken and only the dummy output is available. After "pulseaudio -k" audio again works. Here's what I found in the logs:
$ journalctl --since "1 day ago" | grep pulseaudio Mar 17 19:40:51 coulson pulseaudio[9447]: W: [pulseaudio] sink-input.c: Failed to create sink input: sink is suspended.

The "Failed to create sink input" seems to happen on every resume but only some times does it actually break. Don't know if the ofono message is related or not.
