Since some recent updates (10 days ago) my laptop got problems with reproducing videos (Facebook videos don't open) and streaming videos (like movies from Putlocker) have no audio.

On Chromium it's almost everything ok, though sometimes on Youtube I have to refresh the page to start the video.

I was using freshplugin before the update and everything was working. After these issues I installed Flash (removed freshplugin automatically) but nothing changed.
