Stop sound playing when choosing another sound declaration

Hi all you gurus out there!

In my travel project ( www.jrthibault.ca/europe2015/rhin/carto ), I have a map of the Rhine river in Germany. On it, there are a few buttons to play different sounds. Up to know, I programmed clicking on the map to shut down any sound playing.

This is probably not the most efficient way to do that. Is there a command to shut all sound playing.

Another issue is that the “Loading” message does not show iven if I checked it in Hype. It would be nice this to work because a huge map is loading while one see a black background. This is part of a much bigger project www.jrthibault.ca/europe2015/rhin

Thanks for your suggestions.
