I experience this as well and it does in fact happen quite frequently, but at least in my case it's cause is pulseaudio, that crashes from time to time. However, the crashing pulseaudio daemon should not tear down the indicator-sound, should it?

Well it shouldn't but I guess if Pulse can't handle the service querying the current volume level I have little way around this. Will point this bug upstream. This part of the indicator sound code base has not changed since this time last year and this is the first time I have had a bug like this reported. Will keep it active on indicator-sound, I am currently refactoring my pulse code.

Okay this should be fixed in the last release, so as if the pulse server has gone down then the controls (mute and volume) should be disabled. This will ensure the pulsecontext is not null. At least the indicator will not crash but it does not solve the problem as to why the pulse server is going away. Going to mark this as fix released for now. If you experience the pulse server crashing again please file a new bug against the pulseserver project (one of the projects affected by this bug)
