I have recently developed an issue with my laptop. Whenever I press the mute button (f6) the audio is muted, but the little light next to it does not turn on. I have tried updating windows and reinstalling graphics, keyboard, and audio drivers. I have an HP Pavilion 15z Touch. I do not believe this is a hardware issue because I had this happen a few months ago when a windows update messed up the graphics driver which in turn impacted the audio. I do not know how this was fixed, because I took no action to fix it. Not sure if that relates to this or not.
Thanks in advance.
