Hi guys! Please help, i got lost in HDMI and optical cables. So how many HDMI cables do I need if i am connecting my Blue ray player and TV to a receiver? Do I need an optical cable for audio or HDMI will do? Thanks!
If your receiver receives and outputs both sound and video thru HDMI, you'd need HDMI cables from each thing you attach into the receiver plus one extra to run from the receiver to the tv.
If your receiver doesn't process HDMI sound, you will need one HDMI for each item into the tv and one optical cable from each item straight into the receiver. Turn off the tv's sound. Changing inputs as necessary.
