I have a problem with the sound???
When I listen to the radio using the internet, I have sound. i went to System and Sound and everything is fine. I did all the Tests and everything works fine.
When I connect up for example to Jukebo.fr or other sites to listen to music videos, I have no sound. I check few website to make sure it was not only on one website. This is when listening to music videos.

What do I need to do??
