In the webpage https://www.sonos.com/support/en-us/sonos-user-guide/index.html#t=sonos-user-guide%2Farc%2Farc.htm , it states that:   Arc’s advanced processing creates five phased-array channels that deliver sound to your ears from all directions. What are those five channels? Where do the height channels fit in there?

Hi, I am planning out some TV walls for a client and would like to include Sonos Arc. The plan is for the Arc to sit on a recessed shelf directly beneath the TV. There would be 20cm clearance between the top of the Arc & the top of the recessed shelf, would this setup adversely effect the sound? Would be very grateful for everyone input 🙂

There’s been a lot of confusion on this forum (and others) about Atmos compatibility for the Sonos Arc with non-eARC TVs, especially where the Apple TV is concerned. I have a 2018 Vizio E-Series and after reading entirely too much information on the subject, I still have absolutely no idea if I’ll be able to get Atmos sound from my Apple TV 4K through the Sonos Arc. Seems like a 50/50 chance at best. I’ve just pre-ordered an Arc and should receive it by the end of the week. I’ll test Atmos compatibility through my E70-F3 via both Apple TV 4K and the built-in apps. In hopes that it will help other E-Series owners, I’ll post my findings here. And if I’m able to get Atmos one way but not another (I’m assuming that if anything works, it will be the built-in apps), I’ll post my (extremely subjective) thoughts on Atmos vs. Dolby Digital Plus sound quality For what it’s worth, if anyone has any questions or anything they’d like to know, just ask - I’m happy to test as much possible to help

Hello, What kind of HDMI cable (specs) is required to connect the Sonos Arc’s HDMI port to the TV’s HDMI eARC HDMI port?   Thank you 

I have read through some of the topics about this already, but most don’t seem to give a solid answer on projectors that do have HDMI ARC.   My plan originally was to get the Sonos Playbar+Sub+Ones with an HDMI switcher (for the optical audio) to go to the Optoma Cinemax P1 UST projector. I just learned about the ARC and it’s Dolby Atmos compatibility. The projector has HDMI ARC and states compatibility with Dolby Atmos. However looking through the forums, I’m not seeing a solid answer on if and how it would work with a projector that does have HDMI ARC (not eARC though). We would most likely only have 2 inputs to the projector anyway, so I don't think we would need an HDMI Switcher anymore.    Can anyone provide some insight into this?

Hey guys,   I recently bought a Sonos Arc and I would like to say it is a wonderful product. I’ve plugged the Arc soundbar in my Samsung Q70R(through ARC HDMI) and it found the Arc with one go and that it is Atmos compatible. I enjoy netflix shows with atmos and they sound great. The only issue I’m having is when I’m trying to play games from my PS4 Pro. There is a clear audio delay. I select Bitstream Dolby on PS4 audio settings The only way to fix this is to switch to PCM which is stero and quite lame when you hear the dolby way.   Any of you encounter the issue and how to fix it? Will there be patch for the Arc or something?   Thank you!

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.

Hi Sonos,   it’s great that you launched the ARC but why limit that with just front height channels? Why can’t you allow us to add rear height channels using ceiling or ONE SLs speakers? It would blow everything else out of the water...plus it will give us true Atmos experience with physical speakers?  

With the recent release of the S2 OS; I wanted to ask if 7.1 could be available in the future?   I know this question has been asked before, but I don't know if anyone has clarified if this is a software or hardware limitation.

Hi all, I’m new to Sonos Community and just bought the Arc as my first product since it had Atmos support and good reviews. I’m a general noob when it comes to these things.    However I’m not sure how to get Atmos to actually run. My Sonos app shows the audio as just Dolby Digital 5.1 no matter what I do.  It never shows Atmos playing.  I’m running an LG CX and the Sonos ARC over eArc. I have audio set to go through hdmi out(which is the Sonos ARC) and all 4 of the  HDMI’s audio outputs are set to bitstream. My setup is Sonos Arc by itself no Sub or surround speakers.    Was trying to Watch Jack Ryan on Amazon Prime Video via FireTV stick 4k.    The TV show supports ATMOS and so does the fire tv and the prime video app and my LG CX TV even has native Dolby Atmos decoding and supports passthrough. It even shows audio outputting as Atmos on the Prime TV show.     I know that Atmos format itself is a container and streaming services use Dolby digital plus as the track. So my questio

I’m a bit lost on this.  I have a new Sonos Arc. I Have it hooked up to my Samsung tv which has eARC. I have an Apple TV. I am getting Atmos from the Apple TV Netflix and also Dinsey +. However oddly, the my iTunes movies which say they are Atmos are not coming through in Atmos and default to Dolby 5.1. Why would it play the other services from Apple TV with Atmos but not iTunes movies I have bought ?

Very annoying, when I switch off my television and back on later (even if it's after 20 minutes or so), the volume is set back to 0. Have tried it without the Sonos beam (so only television), but that works correctly.   Any suggestions? Running the latest software.

Very excited about the Sonos Arc, but from the first moment I was so disappointed with the sound from the base! Its plenty punchy but sounds like a old tatty speaker I had in the 90's. I'm gutted and its unlistenable - please say you have a fix soon or its being returned 

Hello! So unfortunately, I’ve got a pretty old TV with an ARC port that tops out at stereo output rather than 5.1 (it’s a Panasonic VT65 plasma). I’m currently using the onboard speakers and I’m interested in getting the Arc and Sub as an upgrade. First off, I’m aware I won’t be getting Atmos with this setup (it’s a good excuse to upgrade my TV in the near future though...) But the onboard speakers just aren’t cutting it at all (especially for movies). My question is whether the Arc will process the frequencies from stereo sources effectively, e.g. will it direct the lower frequencies to the sub and separate the left and right channels in a way that gives me a good audio experience? I suspect it will, as a lot of content out there is stereo only, so I imagine it’s built with that in mind.  My concern though is that it’s going to take the signal, only utilise two drivers in the soundbar, and disregard the sub entirely.  Is the Arc capable of ‘up-converting’ in this way? Many thank

I cannot seem to get the IR repeater to work.  It's enabled in my app but I'm steadily having to raise my arm with remote to go over the Arc. Am I missing something here. There is only a on or off option in the app.   

My tv is not quite flush with the wall perhaps due to the mount itself which is a Kanto FMX3. The tv is an LG 65CX OLED. It is mounted fairly high on the wall over a gas-only (non wood burning) fireplace. The tv is slightly tilted down because it is mounted high on the wall. With the current tv mount, the bottom of the tv is approximately 8” or more from the wall. If I wall mount the Arc, the top firing speakers will look up at the back side of the tv and the tv mount. This seems far from ideal for Atmos playback. This is also assuming Arc needs to be “in front” of the tv so the top firing speakers can bounce sound off the ceiling.   I currently have a Playbar but was really excited to get Atmos. Will I need to cancel my Arc preorder or should I look at different ways to mount my tv? I am willing to sacrifice a swivel function to get the tv closer to the wall because I highly doubt I’ll need that but tilt is a must due to the mounting height.   Any other issues I should be aware of

My Sonos Beam still has a lip-sync delay and i’m now considering an optical switch as many have said this solves the problem.    How does this work exactly - i have searched you tube and can’t see anyone giving instructions to complete novices as to how to set this up. Have i got this right    Tv’s Arc hdmi to the switch’s hdmi slot that says ‘out’  Optical adapter supplied by sonos into the slot that says toslink and then back into the beam.   Will that then get rid of the lip sync?   If i then put an amazon fire stick into one of the switchers hdmi ports would the sound play through that hdmi channel?   It all seems very confusing - i love the sound of sonos but the audio delays are maddening.   Any advice would be appreciated.   This is the switch that has been recommended.   https://www.amazon.co.uk/Techole-Aluminum-Splitter-Switcher-Projector-Black/dp/B07KSYS2L4/ref=sr_1_1_sspa?crid=3HBURFEEVYAQW&dchild=1&keywords=hdmi+switch+4k&qid=1592232631&s=el

Hi All Have just taken delivery of my Sonos Arc and have a new TV coming as well. I was planning on hanging the Arc under the TV on my wall bracket but I have read that there needs to be a gap between the TV and the Arc which would leave the brackets visible. Is it a definite no to hanging it directly under the TV with no gap?  

  Hi all, this is my first post in like 10 years so be gentle! But after days of updating my knowledge of sound formats etc. I wanted to check if I’ve figured this out!    I have a new Sonos Arc,  Connected to an LG B7 OLED (via HDMI Arc)  which is connected to an Apple TV4k.    I can get Dolby Atmos content playing fine from Netflix, Prime etc. And Infuse, all from my ATV 4K.  but when I play Dolby Digital plus (E-AC3) non Atmos content on Infuse it defaults to DD 5.1 on my Sonos app.    Ive tried every conceivable combination of settings Across the tv and ATV to get Dolby Digital plus to show in my Sonos app, when watching non atmos DD+ content, but no go.    If I use the Onboard apps like Netflix etc I also get Atmos as with the ATV...  BUT if I use the onboard Tv version of Plex to play the same non atmos DD+ files, I get Dolby Digital plus showing in my Sonos app!    So I think the answer is this.. but wanted to check I wasn’t kidding myself.    The  ATV 4K carries Atmos

I have reached out to OREI regarding two of their products that indicate they both support HDMI-ARC (Audio Return Channel) - either the UHD-402 or UHDS-402A. My TV has an HDMI-ARC output but delivers a audio lag to the Sonos Beam.  Up until now, I have been using a Cable DVR with two outputs for my source.  The Optical output from my Cable DVR to the Beam (with the Optical/HDMI adapter) and the HDMI output from the Cable DVR goes to the TV.  I also want to be able to connect additional sources such as BluRay or a streaming like Roku or Chromecast. Three questions: Will this idea of extracting the HDMI-ARC work with the Beam? Anyone have experience with either of these two products? Which one of these is best suited for my needs?  I have had three emails with the company but not quite getting the communication that I need to make a best decision.  The link for the two products at the company’s web site are: OREI UHD-402  https://www.orei.com/products/4k-4x2-hdmi-matrix-switch-by-o

Hello, Got my Arc last week. It’s connected to LG C9 with eARC. On the TV there is a setting for volume normalization and it was never an issue. Now after connecting to Arc I’ve noticed that there is very noticeable problem with one app. Checked the audio and it’s DD2.0. Same as HBO GO which has no issues so it’s not dependent on source type. So, what can I do now? Apart from always remembering to lower my volume by half?

I can’t really understand how thinking has gone when possibilities for controlling both TV and Sonos product is going in the wrong direction when a new product, Arc, is launched. Since I only have access to ip-TV and need to use HDMI for connection from box to TV I cannot use HDMI ARC. The old Playbar was still possible to control via Samsung remote and digital output but there is no response whatsoever with Arc. Disappointing development when I went out of my way to exchange my newly bought Playbars for new Arc?

Nice link here summarising the limitations of Atmos via HDMI-ARC connection https://community.cedia.net/blogs/david-meyer/2018/06/25/dolby-atmos-over-hdmi-arc   while E-AC-3 can support up to 15.1 channels of audio, it's well beyond the HDMI ARC spec. Even getting 7.1 channels to pass is a stretch, so even if the stream contains object metadata, it will lack the resolution and height speakers.    This seems to clarify what my ears have been telling me over the past few days, compressed Atmos in a DD+ stream just sounds too overly processed and is lacking clarity.

Cannot work out how to set up up a stereo pair of 2 x new Sonos Five's as front speakers in a 5.1 setup, using playbar, sub and 2 x play 1 as rears. Can't find anyway to set the 2 x Fives's as front L&R and use playbar for speech, which is how a 5.1 system should be set-up? I can only add 2 x Fives's as fronts on their own, setting them up separately, when I pair them to the surround it sounds terrible. Says on Sonos Website that Fives's are suitable for use as surround speakers? Help! Looks like they will be going back to Sonos!

I have 2 Sonos surround systems in my home. I just updated both with new Arc sound bars. Now when I try to run the TruePlay set up it says there is noise interfering and it won’t complete the setup. I have tried several times in both rooms at various times night and day making sure there was no ambient noise. No fans, motors, outside sounds, voices, etc. fails every time in both rooms. When I ran the TruePlay set up in the past in the same rooms, with the old PlayBars, the test worked first try every time. Any suggestions?
