Understanding ARC from TV to Receiver
I'm looking to upgrade my TV but don't want to update all of my equipment. If I got a 4k TV and watched Nextflix, Amazon, and Youtube on the TV I still want to have those sources play audio through my receiver and speakers. My receiver has HDMI 1.3a ports and I don't think audio return channel (ARC) was enabled until HDMI 1.4.
I'm wondering if this matters for a TVs local apps. If I hook up the TV's HDMI ARC output to a regular input of the receiver shouldn't the receiver understand the audio just like any other source? Is ARC about passing through audio from a separately connected source (such as a blu-ray player) connected directly to the TV? Does my receiver need to support ARC to hear sound from the TV's local apps?
Thanks for the help!
