I just tried to make stopallsounds(); work on this demo
http://www.panoramas.dk/panorama/krpano/vtour1/tour.html
I have tried everything even included it in the command for the thumbnails like this
set(events.onclick,null);closethumbs();stopallsounds();loadscene(get(linkedscene),null,MERGE,BLEND
but it does not work.
onstart=" stopallsounds(); "
onloadcomplete="stopallsounds();"
does not work
Only way to do it is to make a fake sound with no sound.
