I reinstalled PulseAdio beacause I my indicator-sound just disappeared, but it didn't help.
Strangely, I have installed indicator-sound and still don't have that sound control. Nay, I don't even have any settings in "Sound Settings":
I ran "Volume Control PulseAudio" from unity launcher and I got this:
So I ran start-pulseaudio-x11:
$ start-pulseaudio-x11 Connection failed: Connection refused pa_context_connect() failed: Connection refused
What Can I do to fix it?
