Hello, I have a problem with my laptop asus n53jg and not found help how to resolve it. Before with windows 10 have a sound and picture... now with win 7 have only picture in TV not have sound on tv only have in the laptop I dont know why is this. Have all latest driver for this laptop intel hd ,nvidia and etc.

When connect with the HDMI to tv windows seen this in device manager only MONITOR . In Sound ,playback devices not seen HDMI or my TV ... not have disabled or hidden I enable this option and again not have hdmi and tv .

I seen only speakers and Realtek digital output devices (when set it to standart also not have a sound)

Any idea how to solved it ... and sorry for my english .
