these screensavers have sound, can be muted from settings or even better by opening the win 7 volume mixer just after viewing preview you can reduce the music to next to inaudible. These screensavers work best with proper codecs installed (such as k-lite). if theres any problems please let me know in the comments. [source **video**](http://www.megaupload.com/?d=GB0J7BO1)
