The hotspots are just regular hotspots with mp3 files attached to them. Using the Panotour GUI, you can only assign one image to a sound hotspot. Furthermore, if you click on more than one image, all the sounds are playing together, which is not what I wanted. I have updated the virtualtour.xml file in order to change the url of the image when starting and stopping the sound, and to close all playing sounds before starting a new one.
It all works fine in flash, it gives exactly the effect I was looking for, but unfortunately it gives a really weird effect on an iOS device: the small speakers seem to move randomly in the image: click on any sound, then move the image with the mouse, some of the speakers are coming along with the image, whilst others stay at a fixed place in the browser. I do not see any pattern in the movements, it really seems random to me.
Does anyone have a clue on what is going on, and how it would be possible to fix this for iOS output?
I tried already various things, like resetting the ath and atv positions of each hotspot when changing its icon, but nothing works
