*SOLVED*
Hey guys! Not a frequent visitor as I have had my setup up and running for a handful of trouble free years. Just recently bought an 8 series 75" samsung 4k TV, and an 8 series 4k player from samsung. Quickly realized that my Pioneer Elite receiver doesn't pass the latest HDMI, so I was only getting 1080. Running directly from my player to the TV I get gorgeous 4k, but of course I lose my sound.
So how to connect this up? Or can I even do it? I quickly see there is an extra output on the back of the 4k player, an optical audio out. HAZZA!! I have an optical input on the receiver! So I hop on over to Amazon and get one here in a couple days (standard toslink digital audio cable). Cable fits into the 4k output just fine with a nice click, but doesn't fit into the input on the receiver at all. although a similar shape and same basic size, it's a different plug. DAMN! Attached is a picture of all three (sorry for the fuzzy pic of the cable, youll get the idea, im sure).
So what is the story? Can I not use this audio input on my pioneer? I don't want 4k with my audio system missing from the equation. I'm sure I missing something simple... I think there is a different optical plug that I just can't seem to find with my google-fu.
Help, audiophiles!
