HDMI (ARC) Question
I would prefer to not buy a new receiver with my 4k television upgrade. I really only use two components in my setup. I have a turntable and an Xbox One. I use the Xbox One for everything including gaming, streaming movies, streaming audio (from the cloud and local network), and Blu Ray movies.
Here are my questions. When I upgrade my Xbox to the 4k compatible Project Scorpio, I plan to run its HDMI directly into my Samsung KU6300 television because my old receiver does not support 4k video. The TV has an HDMI (ARC) port and an optical digital out. I need to get the audio back to my Yamaha RX-V863 receiver which appears to have optical digital inputs and HDMI inputs. What exactly is the HDMI ARC port, and can it be used to send the audio signal back to my receiver while the TV is set to a different HDMI input? Are these optical digital ports compatible? Are there any disadvantages to using the optical digital cables?
