Can someone help me understand ARC as I've never had to use it before but will do with my new sound bar since it only has 2 HDMI ports. I have an HTPC and Sky which will connect directly to the sound bar for Atmos duties. My PS4 will need to connect to HDMI1 on my TV and the sound bar to HDMI2 as it is ARC enabled. I assumed this means that audio from HDMI1 would be returned to the sound bar via HDMI2 but I just wanted confirmation of this? Thanks!
