While the video quality has always been 1080p, the audio has undergone several changes during the years. Sure, there are smart people successful getting the audio into the TV but in fact the HDTV audio is far from their best performance.
However, if you can use HDMI of the laptop connect to the HDTV, why you didn’t. Another case of HDTV connect to laptop via HDMI is able produce the sound in some programs but some others is not then you can try this solution.
If you have sounds already playing on the laptop, then you must switch your default to the HDMI then go and re open the program like iTunes.
Any other program playing sounds on your laptop speakers will continue to play through the laptop speakers…
