Just run your HDMI cable to your soundbar from the Blu-ray player your arc HDMI out on your soundbar to your TV arc port. Everything should be fine with that The audio out only on the Blu-ray player is for people who want to run it to a sound system for audio only. I do not use that and I have a Dolby atmos soundbar. From Vizio the elevate if your TV supports Dolby Atmos pass through you can run the Blu-ray player directly to your TV and then have it coming from the arc.port down to your soundbar. Going from the Blu-ray to your soundbar would be best in case you want to play just music CDs in there you don't have to have your TV on for that.
