This is something I was surprised to find isn't available in Safari. It's a standard option in IE and Firefox. The closest I could find was a program called
Detour, but it isn't available for Intel-based Macs. Does anyone know of an Intel-based program that would accomplish this? It's really annoying to be listening to iTunes while surfing and have some idiotic website blaring some obnoxious sound or music on top of your music. Ad-blocking is not an option, since the offending sounds aren't typically from ads, but from the sites themselves.
