Display is great, no problems, but the sound keeps going out. It is because the SPDIF Interface/Intel WiDi keeps going to mute automatically on my Win 8.1 HP ElliteBook 9480m brand new laptop. All HP drivers are up to date. Below is a screen capture of what goes wrong. To get sound back we just move the slider up and turn off mute, but it will go back to mute within a few seconds. Thank anyone in advance for their help!!!! THANK YOU!!!
