This is all volunteer so a first search came up empty for me. BUT since I run into ARC failures too often I simply add an optical cable and I'm done.
i bought a samsung hw-e350 sound speaker system. After 1 day of having the speaker it just says no arc on the led screen so the first thing i thought of was maybe i need to get a better HDMI cable so i bought a brand new one and it still does not work. The strange thing is when i connect it upto my xbox it works. Strange. I have a samsung UE40D6100 smart tv. Please help me
