I made a simple application using Phonon to loop selected audio files. It works perfectly fine on my development PC. When I copy the .exe to a new PC the file selection part works fine but phonon parts don't work at all. My audio doesn't get started.

In my application folder I have the application file(.exe), three dlls I require for the application (phonon4.dll,QtCore4.dll,QtGui4.dll) and a folder called phonon_backend which contains phonon_ds94.dll
My applications gets launched perfectly but is not performing any phonon function. My target PC is Windows 8 and does not have Qt installed. (I don't think that'd be an issue though)

Please Help.
