Hi, Relative novice to Linux and on the verge of throwing my machine out the window - please don't make me resort!! Basically, I have done a fair amount of customising of late and suddenly I have no sound on any web-based streaming service (egs I am particularly interested in above!) There are no problems getting sound in VLC, Banshee or Amarok so I am pretty sure it's not a hardware issue. Have done a good trawl trough these pages and the best suggestion was to install Real Player. I installed version 11 no probs by following the instructions; Real Player works fine but still no Youtube sound! Played with various settings, tried installing a few codec / plugin packs and have had no joy - arrggghhhh!! If anyone would be kind enough to save my sanity, I would be most grateful, Thanks in advance, Will
