Thanks droidbug. I have already tried this before. Soundbar has HDMI 4k pass through with ARC (Two HDMI ports). I will try the whole process again after a factory reset and come back if successful otherwise will wait for FW updates. Maybe there is a fix for this via an update.
Volume leveling or normalizing is pain (especially at night) and I am also looking for a solution for that, anyone please help. Thanks in advance.
