Steps to reproduce:
1. Go to this link https://dl.dropbox.com/u/20803261/NWTest/index.html and load the game in any browser. You can also use the preview option in Construct (F4).
2. Download the .capx file and export the project with node-webkit.
On any browser, the audio plugin will detect appropriately if a looping sound is already playing and won't restart it again every time we go back and forward.
However, if we try the node-webkit version (win32), it's obvious that the loops get stacked when we return to the first layout after pressing the GO - BACK buttons, resulting in several instances of the same audio playing at the same moment, therefore altering the whole experience.
Node-webkit detects the looping sounds already playing and ignores the stated order of playing it again at the start the layout (for example, when navigating through menues).
