I'm trying to hook my HP laptop up to the tv to use netflix. Had a HDMI cable and would get picture when it wanted to but no audio. Went out and bought another HDMI cable. Now I get crystal clear picture, but still no audio. Wondering if there is a setting that I need to change or if my laptop isn't set up for this kind of hook up. I also noticed that in my sound menu, that it is not detecting that my HDMI cable is hooked up. But I'm still getting the picture on the tv screen.
