Question

Intermittent Atmos - Samsung Q90R

Set up the Arc on Friday. Played Atmos on both Netflix and Amazon Prime Video. Saturday morning the Atmos had switched to 5.1. I’m in the UK and thought perhaps it was due to lower bit rates due to Covid-19. Saturday night Atmos was back. Sunday and today, just getting 5.1.

 

Is anyone else experiencing similar issues or perhaps has an idea why this might be happening? Very frustrating.

I have a Samsung Q90R - it passes through Dolby Atmos through DD+ . Netflix and Prime should give you Atmos

How do you have yours set up and how are you now to tell it’s atmos or DD+? Thanks in advance

I don’t believe that, the Q90R does not support eARC.

This chart is helpful:

@John76, eARC is not an absolute requirement for Atmos. Atmos can be carried on a normal ARC connection using DD+. there are definitely issues with older ARC-equipped TVs not being able to pass through the DD+/Atmos stream though - my 2014 Vizio P series was able to pass DD+ but not DD+ w/ Atmos so it was upgraded to an LG C9. there are multiple reports (like @eugeneclh here and @Geoffa30 original post) of newer ARC-equipped sets working with Atmos to the Arc.

@Geoffa30, sorry i can’t add direct experience for your Q90R but have found my best overall experience when all of the HDMI related settings are set to Auto and Bitstream where possible so the apps and, if you have them, external inputs can detect the capabilities when each powers up or is activated. Currently, the Arc doesn’t support LPCM so Bitstream is necessary.

    @John76 , I have a 2019 Samsung Q60R, no eARC. But I can use the internal Netflix and Amazon apps to get Atmos on the Sonos Arc. The “about my system” shows Dolby Atmos (DD+), it is lossy Atmos though.

     

    @Geoffa30 , I get Season 1 of Jack Ryan in Atmos from Prime. But for season 2 , Carnival Row and the other one content that are supposed to have Atmos, I can only get 5.1. Don’t understand why.

        As people have been trying to tell you, Atmos can be carried via TrueHD/MAT/LPCM (requires eARC) or via Dolby DIgital+ (requires ARC or above).  You can most certainly can get Atmos over ARC via DD+.  Matter of fact, most streaming sites only offer Atmos via DD+.

          My mistake, good to hear certain TVs can pass compressed Dolby Atmos using ARC.

            Seems we were having internet issues at the weekend. Finally sorted last night. Now both Netflix and Amazon native apps on our Q90R are showing Atmos.

              geoffa30, Apart from Jack Ryan Season 1, what other contents in Prime are you getting Atmos from?

              I can’t get ATMOS on my Q90R, Dolby digital plus option is grayed out in settings.  Is the ARC HDMI connected to the one connect box or straight to the tv?
