My HP ENVY dv6 is running Windows 8.1 64 bit. It plays notification sounds when I get a new e-mail, but it won't play any other sounds. For example, I can go to YouTube, pick a video and hit play, and I will hear no sound. I doublechecked to be sure that the video itself is unmuted and that the speaker on the video itself is high, as well as checking to be sure that I have the sound set to high on the laptop itself. Nothing works.
I've tried uninstalling and reinstalling the driver, and that did not resolve either. Any insights?
