Further to the previous answer, it depends on whether or not your soundbar supports eARC or just basic ARC. You need eARC at both ends to get Dolby Atmos, etc. My soundbar only supports basic ARC but it can pass through the 4K HDR signal from the Bluray to the AG9 TV. So I’ve connected the HDMI output of the Blu-ray to the HDMI input of the soundbar. I then run an HDMI from the ARC output of the soundbar to the ARC connection of the TV. That way, the soundbar gets the full uncompressed audio and the TV gets the Blu-ray video. The other devices can be connected to the TV’s HDMI ports and their sound will go through the eARC to the soundbar.
