hi i have windows 7 ultimate upgraded by anytime upgrade from the recovery windows image and when playing any sound only the speakers under the screen are playing the sound while both the front beats speakers and the underneath subwoofer dont play anything at all. i've tried the solution presented here with no results (http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio/No-sound-from-sub-woofer-or-Beats-front-speakers-on-dv7/td-p/2261929)
tried installing another versions of idt driver also with no results
when entering the configure menu on the speakers device in playback devices it only let me test the stereo speakers under the screen, no other devices or speakers appear available to test
if someone can help me here it would be greatly appreciated
