I had someone downgrade my dv7-7243cl from Win 8 to Win 7 and they got most of it right but they used a microsoft audio driver that works but it doesnt allow the Beats Audio speakers to play very loudly. I looked on HPs website and tried two different drivers that were for win 7 laptops but neither worked. I need to find the right driver that will be compatible and give me full performance. I did look in device manager for the IDs on the audio controller and heres what was listed.
HDAUDIO\FUNC_01&VEN_111D&DEV_76E0&SUBSYS_103C181C&REV_1001

If anyone can help me that would be much apreciated. Thanks Carl
