Follow these steps: 1) Plug in headphones in your laptop 2) Adjust volume to 50% with gnome controls 3) Open youtube.com and play any video The (system) audio volume is pushed to 100%. Then, 4) Lower the volume (again system volume, not youtube volume) back to 50% 5) Select any other video 6) The system volume is again re set to 100% Repeat all the above step without headphones plugged in (using laptop integrated speakers) and the problem will not occur.
