I have an Asus laptop N550j and I have a samsung smart tv and I have played sound from my old HP laptop and it worked through the same HDMI cable to my tv, but my new Asus does not play through it on my tv. I have tried reinstalling the drivers for the audio and that worked once and tried doing it again but it did not work. I have also tried playing sound through a different tv but that did not work either. Any suggestions would be helpful thank you. The Asus laptop is Windows 8 and the HP laptop was Windows 7. Not sure if that is the problem or not. Also, the audio playback manager also does not even recognize the tv. Thank you.
