I currently have a surround set up with the Sonos Arc and two SL ones and gen. 3 subwoofer. When I’m playing a movie with Dolby Atmos it is not showing in the sonos app that its coming through as Dolby Atmos. Instead it is showing pcm 2.0.. I have my system playing through a Samsung QLED Tv model Q80 . This is driving me nuts!!! Any suggestions would ge appreciated!

Alright I tried using the HDMI cable that came with the Sonos ARC and still nothing. I tried playing The Tomorrow War movie from Amazon Prime and still showing PCM 2.0 on my sonos app. I even tried switching the sound setting to pass-through and nothing. I’m running out of ideas any more thoughts?

Very odd. At the very least you should be getting Dolby Digital Plus audio.

Try this:

First, make sure the TV has the latest firmware installed. Then disconnect everything from the TV including the Arc. Unplug the TV and Arc from power for a couple of minutes. Plug them both back in but keep everything disconnected. Make sure Anynet+ (CEC) is enabled on your TV. Then run TV Setup in the Sonos app. When the app instructs you to, connect the Arc to the TV’s HDMI ARC (HDMI 3) port using the Sonos-supplied HDMI cable. When the Arc has been successfully connected, connect any other device you have to the TV. Set eARC to Auto and Digital Output Audio to Pass-Through (or Auto) and test again.

rtings.com says “ The Samsung Q80A supports Dolby audio formats, including Dolby Atmos via TrueHD through eARC. For it to work, enable HDMI-eARC Mode and set Digital Output Audio to 'Pass-Through'.

Mr. T

The content I’ve been trying is Disney + , Netflix , amazon prime.

Are these the Samsung native tv apps or are you using an external media device (Apple TV, Fire TV Stick/Cube etc)

The picture setting above states Pass-Through is only supported when the source is HDMI, so has no impact if you’re using the Q80 in-built apps.

I use my apps through Roku system not the apps directly on the TV.

Well this is useful information. Which specific model Roku device are you using? Have you changed the audio settings on the Roku to play Dolby Digital Plus audio?

The Roku I’m using is Roku Streaming Stick 4K +. I have not changed any audio settings with the Roku.

This is probably the problem. Change the audio settings on the Roku to Dolby Digital Plus.

NOTE: There is a chance that Dolby Atmos is not supported on Netflix on the Roku Streaming Stick+. Use the TV’s native Netflix app or the Netflix app on the Xbox instead. And you need a premium Netflix subscription.

That’s actually a good idea! I’ll have to double check my audio settings on the Roku.
