Hi, I have a 55" TCL Roku tv model number 55S431. When I plug my laptop into the tv via a new, tested, HDMI cable all I get is the video signal, no audio. I still get audio playing thru the computer but not the tv speakers. I've tried all the inputs including the HDMI 4 input with ARC support. Any help will be much appreciated. Thanks in advance.
Go into your computer settings> system> sound> output device> if it has your tv model listed choose it over Realtex.
