I have a HP Pavilion Dv6 Notebook PC Product # QE071UA#ABA. The light on the speaker button (F11) stays red when I tap on it, but I can see the sound bar and icon in the center of the screeen. I am unable to use the mouse to adjust sound. When I hover over the speaker Icon on the toolbar it says that no speakers or headsets are plugged in. When I click on the icon, It tries to trouble shoot the problem, but itc an not detect the problem. I have shutdown the laptop. unplugged the AC and battery, held the power button down for 60 seconds, plugged the AC and battery back in and restarted the computer. I have also ran a system restore back to before a critical update on 8/27/14. So far nothing has helped. The AMD high definition audio device states that it s working properly. Laptop has Beats Audio. Using Windows 7.
Thank you for the help.
