I have tried some of the fixes I found in this support community (uninstalling the Realtek thingy and reinstalling it) but none of them have worked, I have checked that my Windows is fully updated and have checked for any updates through the HP Support Assistant. Neither of the lights work any longer which makes it more confusing when using my laptop, the laptop is still able to mute audio and disable the microphone, it just doesn't show it through the light too. Hopefully someone can help me out!!
