You'll want to put on headphones or turn up your quality speakers perhaps, in order to tell the difference between the audio playback.
Your comments welcome! And if anyone involved in HP's Elite X3 development is reading this then grab Microsoft's Equaliser code and add it to your OS builds as soon as possible, please. Microsoft already solved this audio problem, just copy and paste the code.
PS. If anyone's curious as to the music being demoed, it's Melanie C's excellent 'The Sea' album.
