Sure.
I have the N2 connected via BD/DVD input on the Sony STR-DN1080 then HDMI1 OUTPUT to LG TV all using AmazonBasic HDMI 2.0 cables.
LG Settings:
Connection > HDMI Device Settings > Auto Device Detection: ON
Connection > HDMI Device Settings > SIMPLINK(HDMI-CEC): ON
Connection > HDMI Device Settings > Auto Power Sync: ON
Sound > HDMI ARC > eARC: ON
Sound > HDMI ARC > Digital Sound Out: PASS THROUGH
Sony Settings:
Setup > HDMI Settings > Control for HDMI: ON
Standby Linked to TV: AUTO
eARC: ON
Standby Through: OFF
Audio Out: AMP
HDMI Out B Mode: Main
HDMI Signal Format: Enhanced
I would suggest trying eArc off if you already have it on as your TV is HDMI 2.0 so will probably not support eArc.
