[ubuntu] No Sound or Devices in PulseAudio

view story

http://ubuntuforums.org – I have been having some problems with my sound recently. I have no sound, and also, no options to select an output device. Please see the attached images which describe this problem. If I type this into a terminal: Code: pulseaudio -k I get the following output: Code: E: [pulseaudio] main.c: Failed to kill daemon: No such process Running this command has no effect: Code: start-pulseaudio-x11 Any help would be much appreciated!
