If you have GetRight installed on your computer, a download management utility and you view a Flash movie that attempts to load an mp3 sound file into the flash player dynamically using the Sound.loadSound method, GetRight stops the loading of the mp3 file and asks you to choose a location to save the mp3 file on your local computer, whether you choose to download the file or not, flash still doesnt load the file into the player, which raises an issue.

GetRight is one of the most, if not the most popular downloand utility and this is the default behaviour of the program, of course these settings can be changed, by removing the hook for mp3 files but Flash alone cannot do this automatically for you, this is a manual process that viewers of your site will have follow if they want to listen to dynamically loaded sounds on your site…

To fix the problem, i assume that by changing the file exstension of your mp3 files to something which isnt registered as a download hook in GetRight will do the trick, but of course, if GetRight actually checks the mime-type of the file instead of using the files exstension, then this will not solve the problem. Changing the mime-type is not only a complex process for novices, it wont solve the problem, because the Flash Player will not play the file if its mime-type is not set to type mp3.
