You need a high-quality cord above 1.6V, preferably 2.0-2.1V, and also, whoever encounters the "falling off" sound via HDMI, I will say right away that you need a short and high-quality cord. I tested (fortunately, there are 7 different ones in their stocks) cords of different manufacturers and categories, well, they are long, and so, I stably earned 2.0V -50 cm, "failures" had already begun at 1 m and sound was not always transmitted, and of course the old ones laces and long ones did not work at all, although on the old cinema from SONY DAV-DZ850M, they worked fine on the last NG, :) karaoke is ours :) In general, I did this on two guides to the TV bracket, hid the wires behind them, well, yes, the color of the TV frame is so-so, well, what is there :) and the gap for two reasons, cooling and control of the TV set from below, had to be left under the fingers!
