The tour.html which is in vtour folder works fine, because that is generated by krpano tool. One step above, there is index.html (which I have created) where I want to embed the tour. In index.html tour showing up but the sound is not working. That is the issue. If you will open the index.html file you will see below error in console.
This message is correct.
All
independent changes can result in something that does not work. Your modifications introduce significant changes to the file structure generated by the KRpano droplet. In your situation, use the native actions of the HTML5-VR Audio Plugin. Then you will be able to control
audiofile to your file and these errors will not occur.
