Pulseaudio is sometimes broken after resume from suspend

[Pedro Côrte-Real]

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

--- Here I ran pulseaudio -k ---

Mar 18 19:08:13 coulson pulseaudio[26606]: [pulseaudio] backend-ofono.c: Failed to register as a handsfree audio agent with ofono: org.freedesktop.DBus.Error.ServiceUnknown: The name org.ofono was not provided by any .service files

Mar 18 19:08:13 coulson pulseaudio[26616]: [pulseaudio] pid.c: Daemon already running.

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.
