PulseAudio Problem

[Sicheng PAN]

Hello,


I have a problem with PulseAudio Volume Control, when I want to open the
programm from the menu, I have an error message like this : « Connection
failed: Connection refused »

With "pulseaudio" in a terminal : 


E: main.c: Failed to create '/tmp/pulse-sicheng': Opération non permise
(french : operation not autorised )


I tried "pulseaudio -D" in a terminal, it return me : 


E: main.c: read() failed: Aucun fichier ou répertoire de ce type (none
of this type of file folder)

E: main.c: daemon startup failed.


Anyone knows how to solve this problem?

Thank you for your help.
