Arc and Sky Q

Hi thanks for reply 

diagnostic conformation number is 

811398398 

Arc is connected through hdmi arc via Samsung connect box the issue only happens when watching Netflix and Disney + apps through sky q if audio is set to Dolby digital plus, which you need to receive Atmos, there is no sound output at all but if I stream direct through the tv thereis  no issue With  sound on either app 

Hello @brents82,

Thank you for your response and diagnostic report number. 

I’ve noticed that some Samsung TVs aren’t passing the DD+ signal through correctly when eARC is enabled.

If you disable eARC within the TV settings when playing Atmos content from your Sky Q box, does this audio issue resolve? 

Hi @Jean C. 

I’m also having this issue. If eARC is enabled then I get no sound from the Sonos Arc. 
 

I can confirm if I turn this off, I do then get sound. 
 

Any idea on a timescale on your developers looking into this issue?

Regards

Frank

@FBhoy86,

Thank you for reaching out information here on the Sonos Community. 

We are now aware of this playback issue and are working to resolve it.

Unfortunately I do not have a time-frame for when this might occur. Please keep an eye out for further information here or on our announcement forum.

I also have the ARC and I am having a similar frustrating result when watching Netflix or Disney+ via connected Roku Ultra with content that is DD+.  Sound cut out intermittently or just goes away entirely. Was told by Sonos tech to just switch to PCM rather than bitstream essentially defaulting to 2-channel stereo (didn’t spend that kind of money for stereo sound); also stated it was a Roku issue. Playing same sources directly through LG TV works fine. Oddly I have received Atmos through both methods, but via Roku it is Inconsistently problematic. 
Sad thing is especially after the Beta test and possible update, I am no more impressed with the ARC (sound quality and stability) as I am my Beam; should have just bought another Beam instead in hindsight. The Beam worked seamless with the Roku. 

Hello @hoffw68,

Thank you for reaching out to the Sonos Community with your issue.

The current reliable workaround is to disable the eARC when using DD+ audio and only enable eARC when you are playing Dolby Atmos True HD audio.

So my aging Denon AVR has no issue dealing with processing DD+ audio and DTS for that matter, but your telling me to essentially switch to 2-channel audio (switch from Bitstream to PCM)? I am assuming that is what you mean by stating disable eARC?

@hoffw68, 

I mean Switch to ARC rather than having the eARC feature enabled on your TV. 

My LG TV doesn’t technically have eARC as an option to enable/disable, but yet it does pass Atmos. So even though I prefer the functionality of the Roku, seems using TV Apps (Tablo, Netflix, Disney+) is the direction I’ll have to take due to limitations between Sonos and Roku; at least if I want improved sound. Either that or switch back to my Beam which sounds just as good as Arc anyways. Thanks. 

@hoffw68 

Understood. The issue seems to only be related to the way that the LG TV is handling and passing on the DD+ signal from the external HDMI source. 

As a Roku user myself, I do understand and this is frustrating from my end as I do not have a good workaround for this specific issue. Are you able to set this back to DD 5.1 rather than DD +?    

Hi folks. Here's an update for all users using Samsung 2020 QLED (LS03T) Range in the US.
Samsung released a firmware update version 1402.1 that may assist in mitigating the issue.
Currently, the update appears to only be available for US models and via a manual USB update.
Reach out to Samsung for further assistance and hope this helps.
We and the community are always here to help.
