A:Answer There are a couple of different options. I use the 1/8 inch Stereo jack from the back of the TV so that ALL inputs from the TV feed the sound bar. Like: Game System, Blu-ray, Cable Box, Etc. I don't worry about "Digital vs Analog" because it is only a short distance, and my sound bar is front speakers only with wireless sub. If you were running a 5.1 or 7.1 sound bar with rear surround speakers, you Definitely want to use HDMI for 5.1 or 7.1 digital surround. My particular soundbar only allows to me to adjust EQ using the analog input. So I get better sound performance with the 1/8 inch jack from the rear of the TV directly to the bar.
