Arc doesn't work with Samsung TV Q95T : If you want Dolby Atmos avoid Samsung Flagship TV's

I bought a New Samsung TV and Sonos ARC Soundbar last week: 

Samsung TV Model QE65Q95TATXXU

Software Version : 1115.5

Connected Sonos Arc to the eARC port 3 on the TV and the Arc only delivers any sound when the eARC is switched off (no Sound on Automatic). The Sound output on the TV is only recognising the ARC as connected to HDMI when it should recognise it as connected to the eARC HDMI port. The Dolby ATMOS compatibility button makes no difference when on or off. Pass through setting makes no difference. Dolby Atmos (DD+) is recognised by the SONOS App when playing directly from Netfix App on TV, this means the TV and SONOS ARC are not talking to each other and not recognising the eARC signal (it should say DOLBY Atmos not DOLBY Atmos DD+). Checked all connections and have rebooted both TV and Soundbar with no success

Not ideal when the TV and Sound Bar cost over £3500, I just want it to work and thats what should be delivered by SONOS.

Spoke to SONOS Support (Xander P) and these are the quotes from him:

It does look like there may be some issues arising when the eARC function on the TV is enabled. DD+ is capable of carrying a compressed ATMOS signal, so you should still be able to experience ATMOS from your Arc. In the mean time however there's no fix for this.

I'm not able to give you a solid answer right now unfortunately, however the Arc is known to work with other TVs so my inclination would be that this is a Samsung issue. We are certainly aware of this however and we are reaching out to Samsung in order to get this resolved.

I would expect this to be fixable via a Firmware update, however I can't guarantee this unfortunately.

We are reaching out to Samsung in order to get this issue resolved. Due to the huge number of TV models and manufacturers, issues such as this do sometimes arise - in any case we are looking in to getting it resolved and we are happy to assist any customers which are affected by this issue.

So basically SONOS are blaming Samsung because the ARC works with other TV's. No firm promise of a fix, not very impressed with SONOS at this point as Samsung could be classed as a major supplier of global premium TV's and you would have thought that SONOS would have ensured their premium soundbar would work with the new Samsung Flagship range, but apparently not.

Suggest SONOS and Samsung get their act together and sort out the issue.

    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.

    The update enables you to turn on EARC but the audio stuttering is now worse. Samsung needs to fix this.

      Hi guys. i’m thinking of getting the Q95T and ARC. And i’m wondering does the one connect box supports hdmi 2.1 and hdmi eARC or do i have to connect the cables directly to TV?

      Interestingly this was the exact setup I was going to buy in 2-3 weeks…

      Q: Considering there’s no fix (I won’t buy a broken setup), should I consider keeping

      • the soundbar or
      • the TV… 

      for my setup? Or wait?

      As far as I understand, there’s also an eARC problem with the soundbar and LG TVs. So I’m totally confused now. :astonished:

      I have to connect my Samsung Q95 T with the Sonos Arc using the optical cable. I am also using Sky Q which doesn’t help. All sorts of lip sync issues which are fine with the optical audio cable but of course defeats getting the Dolby Atmos. I have kept the Sonos Arc on the basis that it’s still slightly better sound than the TV but my plans to buy the additional Sonos system speakers are definitely on hold. Would I recommend anyone to buy a Sonos Arc? No!

      I’m puzzled that this issue doesn’t appear to feature in any of the Youtube videos reviews.

        Hi, Does anyone see the actual volume level with increasing/decresing volume on the Samsung 95T whilst using the Sonos Arc? I only see Reciever HDMI and the + and - symbols, but no volume level

        No, and you won’t. What you see currently is correct, as the TV’s source for sound is the Arc, which is external from the TV, hence it cannot know what level the Arc operates to. 

        If you do need to see what “level” you are at, you can open the Sonos app, go the the “living room” or which ever room shows the TV as the source. You can see the volume level on the app when you toggle with the remote

        What is stopping you from connecting the ARC and the TV with a 2.1HDMI cable?

        Even with the e-arc functionality issue, which does actually not limit the Arc’s capability in producing sound, the ARC is capable of great sound imo. Atmos content can still be played (HDMI cable is a requirement tho, optical cannot support Atmos) and the sounds effects are quite amazing. I have the ARC paired with 2 Sonos One’s for surround and the subwoofer - no complaints here about quality of sound at all!

        I have the same exact TV and the ARC. The ARC and one-connect box I have connected with a 2.1HDMI cable as the one-connect has 1 e-arc functional port and 3 “normal” HDMI ports for other devices (PS4, TV box, whatever). Nothing goes directly to the TV except for the “invisible” cable running from the TV to the one-connect. Hope this helps

          I used the hdmi cable supplied with the Sonos and even bought a new high quality 2.1 hdmi cable with the same result.
