John, my Marantz doesn't pass through 4K HDCP 2.2.
I just rechecked and now I'm getting 5.1 audio. I had made adjustments in the settings (to auto) so I guess it reset after it did the power off after 30 minutes of no action.
I'm warching the power off because some are saying the 4 won't power back up after it powers off (they have to unplug & replug to do a reboot). Mine hasn't done that yet, does take a few seconds to power up with just turning on my TV .
