I have 10.10 and this has been bothering me beyond words can ever describe. I first searched Google with the keywords to the tile of this post and, sure enough, others seem to have encountered this same problem as myself. I tried what was listed but to no avail to my system. Then the following worked:


1. Go to 'Home folder' by clicking on 'Places' menu on top left
2. Press 'Ctrl + H' to reveal hidden folders
3. Delete '.pulse' folder
4. Restart

I sincerely hope this relieves a few headaches and frustration
