Available on June 10th, Sonos Arc is the premium smart soundbar for TV, movies, music, gaming, and more. Arc brings brilliant surround sound in 3D, along with immersive music, elegant design, and voice control built in. Experience shows, films, and games with the precise and immersive sound of Dolby Atmos, and enjoy incredible sound streaming music, podcasts, and audiobooks. 


Extraordinary sound meets elegant design

Eleven high-performance drivers, including custom elliptical woofers and precisely angled side tweeters, produce vivid detail and impressive bass for home cinema and music streaming. Arc's upward-firing drivers create a multi-dimensional soundstage that moves around you, rendering every whisper and explosion with dramatic clarity, detail, and depth. 


With its elongated shape, soft profile, and seamless façade, Arc discreetly mounts to the wall or sits beneath the TV without pulling focus. When mounted, a magnetic sensor detects the orientation and smartly adjusts the EQ to temper bass resonance.


Arc’s sound was specially tuned with the help of Oscar-winning sound engineers to emphasize the human voice so you can always follow the story. The advanced processing creates five phased-array channels that masterfully deliver sound to your ears from all directions at the exact right moment. Use enhanced Trueplay tuning technology to optimize the sound for the unique acoustics of your room, even calibrating the height channels for precise localization. 




You can also make a surround sound setup with a pair of our surround capable Sonos speakers, such as a pair of Sonos Ones, or amplify it all with a Sub for an extraordinary surround experience. 


Some more details on Sonos Arc:

  • Simple to set-up. Plug Arc into power and then connect it to your TV using the HDMI-ARC cord. Bring your phone up to Arc to automatically pair and securely transfer WiFi credentials using near-field communication (NFC).

  • HDMI eARC. Increased bandwidth supports high-quality audio and has lip-sync compensation built in.

  • Dolby Atmos. Play Atmos and Atmos-encoded audio to play from your collection and favorite services through your TV’s HDMI ARC or eARC connection.

  • Ambient light sensor. Arc detects how bright the room is and automatically adjusts the brightness of the LEDs to be visible but not distracting.

  • Automatic remote sync. Arc connects to your TV's HDMI eARC port with a single cable and automatically syncs with your remote.

  • Control your way. Control Sonos Arc with your voice, the Sonos app, your existing TV remote, your favorite music service’s app, or AirPlay 2. Capacitive touch controls for play, pause, skip tracks, adjust the volume, and group rooms just by tapping or swiping the top of the soundbar. LED indicates status, mute status and voice feedback.

  • Smart voice recognition. A four far-field microphone array used for advanced beamforming and multichannel echo cancellation makes sure you’re heard, even when the music is blasting, even when playing in immersive surround sound. For privacy, turn the microphone off with a tap. The LED light is hardwired and will always indicate if the microphones are enabled or if your voice assistant of choice isn't listening.

  • Optimized for your listening. From within the Sonos App, tap Speech Enhancement so you never miss a word, or Night Sound to amplify quiet noises and reduce loud ones so you can enjoy late night TV without waking the entire house.

  • Tune with Trueplay. Trueplay puts the speaker-tuning capability of the pros in the palm of your hands, adapting and optimising the sound of the speaker to the unique acoustics of the room. iOS device required.

  • Low profile and compact size. The dimensions are 3.4 x 45 x 4.5 inches (87 x 1141.7 x 115.7 mm) H x W x D and Arc weighs 13.78 lbs (6.25 kg).

We’ve updated the main thread on the request, but I wanted to share here as well:

We will be adding Multi-Channel LPCM support to Arc as part of a future software update. We don’t have exact timing to share at this point and will update you when we do.

I was about to pre order one until I saw it won't work with the play:1s  I'm currently using as rears with my beam.  Quite disappointed since I only brought it as set around 9 months ago.


Moderator edit for clarification: A matched pair of Play:1s or any other pair of Sonos players that support Sonos S2 are able to become a surrounds with Arc.

Just one more HDMI socket on the Arc is all I would’ve needed to make this an easy buy.

In the interests of simplicity they’ve nice again crippled their product and made it 100x more complicated than it should be.

My use case;

  • LG C6 TV with ARC only (not changing this anytime soon as still want 3D)
  • Oppo UltraHD disc player itching to let loose with some full bandwidth Atmos via seperate audio only HDMI
  • Apple TV 4K (arggggh!)
  • Xbox One Pro ready to output Atmos
  • If I use ARC out from TV will only get downscaled DD+ and will run out of HDMI inputs

I’m already looking for extra HDMI eARC splitters/switchers and I can’t see a way to get the full benefit of the upgrade from my Playbase. I did not intend becoming an expert on ARC and eARC this week but now thinking of buying an Sonos Arc I have to factor this into my decision.

How much simpler it would have been to have another input on the Arc! I hope this wasn’t just about saving a couple of dollars in manufacture…..

Ryan, do the upfiring speakers play a role with non-dolby atoms content?  For example, when streaming music or playing dolby digitial content?

Well the other question is coming up is will the Sonos Arc really receive the HDMI direct like those soundbars …. there seems to be inconsistent answers.   It would take someone plugging and HDMI direct into a Beam to see if really will or not.

But assuming then it doesn’t work - a lot of switches already will extract HDMI ARC so just a matter of time before you can get a switch to do the eARC to the Sonos Arc (mouthful there).

The example Switch had 4 inputs and 2 ouputs (of which one currently can be ARC …. just need updated version that will also do eARC)…. at about $50 a lot cheaper then replacing TV.

A lot of hypotheticals right now - I’m sure a lot of creative solutions coming to get eARC ability for people on many things not just Sonos.   So a TV not having eARC shouldn’t be the biggest concern.


I spent a lot of time looking a few months ago and could not find any HDMI switches that would *generate* ARC output (use-case is a projector that doesn’t support ARC). Many HDMI switches will *accept* ARC input from one off their output ports (since ARC goes backward compared to normal input/output designations) and send that audio as the audio channel of normal HDMI and/or send the ARC channel back to active inputs (say a receiver). But none of the normal ones I found would create ARC from a normal HDMI audio input which is what the Beam requires when you don’t have a TV that will generate the ARC signal. The Beam won’t play audio from a normal HDMI signal - as others have noted it acts as a source device that outputs video and consumes audio over ARC only from what I tested.

I did find exactly one device that would generate an ARC signal either from a normal HDMI signal or from an optical input: https://www.sct.com.tw/ARC01.html The key is the embed functionality (as extract is common). There is no US distributor so I had to order direct from the manufacturer. The device works as advertised with my Beam. My original goal was to get HDMI-CEC working; I have not succeeded at that yet - but it may have to do with other issues in the HDMI switches I have connected. I haven’t diagnosed those yet to see if HDMI-CEC + ARC is viable for the beam with a non-ARC projector.

The ARC01 doesn’t support eHDMI; but I assume a similar device with eARC support would be required to use the Sonos Arc with a non-ARC TV/projector. It also doesn’t look like this functionality is common or widely-sought after given the lack of support in normal HDMI switches. It is too bad Sonos is sticking with a pure-eARC/ARC strategy unless they are willing to also produce useful converters. Love the speakers but dancing around limitations like ARC, lack of DTS support, etc is unfortunate when comparing to other options at this price point.

Reading pages and pages of questions, whether TV’s work with the Arc, or not.

I think, making some kind compatibility chart would a be a wise thing to do for Sonos (if this is, by all means possible).

I am afraid a lot of people will be disappointed, possibly not getting what they expected to get.


While there’s no doubt that such a chart would be useful , I’m not sure Sonos can really do this.  Sonos is following the industry standards and guidelines for ARC/eARC and all the various audio codecs and formats involved.  They don’t own these standards and guidelines, and really don’t have the authority to certify that a specific product is meeting a standard properly.  For the standards they do own, such as the interface music streaming apps, they absolutely can and do certify what works.

That’s not even considering the volume of various content sources, services and TVs out there that would need to be tested, and the possibility that anything can change at any time through firmware upgrade and/or service policy changes.


In the past such data has been collected and organized, in a way, by users in this forum and elsewhere.  Something that would need to happen again. It would never cover all possibilities and combinations, but could be rather useful for the most common situations.

Is a separate wall mounting bracket required for wall mounting?

Yes, there is a separate wall mount bracket, or you can use the Playbar wall mount if you have one.



The above is incorrect. The Playbar wall mount is not compatible with the Arc. You can use the same drill holes when exchanging the mounts, but Arc has a smaller footprint than Playbar. My apologies for getting this wrong. Arc is only compatible with the Arc wall mount available at: https://www.sonos.com/shop/wall-mount-for-arc.html

The connection via HDMI-ARC has a handshake to communicate with the TV to understand if it’s plugged into the correct port. It reads that to determine that the HDMI signal is coming from the TV, and you need to be connected to the HDMI-ARC port on the TV if you want to use straight HDMI-ARC or eARC with the Arc or Beam. Use the Sonos Optical to HDMI adapter if you need skip the TV for any reason. From what I’ve heard, Arc won’t strip out an audio signal from straight HDMI if you connect that in.


Rysn S/others from Sonos - Is it okay to mount the Arc above a TV (like the Playbar) or does it really have to be mounted below the TV given the up firing speakers?

The Arc should be below the TV in best practices. Because of the up firing speakers, you need them to be a good amount of distance from the ceiling in order for the “arc” to get to your seated position. Arc doesn’t support being flipped or having multiple orientations like the Playbar. 



It would likely work, but that’s if you can find an audio extractor/splitter which supports Dolby Digital MAT/DolbyTrueHD Atmos and DD+ Atmos and has an HDMI-eARC port… I’ve been looking and can only seem to find one that has HDMI-ARC support.

Nobody, to my knowledge, has yet found an audio extractor with an HDMI-ARC port which can strip audio from another HDMI input.

There are devices which can take audio from an S/PDIF and push it out the ARC port; there are some able to take ARC already generated by a TV and pass it through. Neither does what’s required here.

Update - found a response from HDfury in avsforum that notes it will not do what we need:


So there is not one product, AVR or other that can solve this for us?

No.  There is not.  I said what HDfury said like 6 pages ago here.  It won’t work because Sonos’ products have HDMI outputs, not inputs.  If this doesn’t work with your TV, you will need a new TV.  Or someone has to innovate a new product designed to solve for this, but I have major doubts that will happen.  It would be pretty complicated given the way the Sonos Arc is designed and it would be a product that in some number of not so distant years would be completely obsolete as all the new TVs will have eArc/Atmos support.

I don’t think it’s quite that bad. There’s nothing on the market, but then there’s been little market driver until now. It won’t be obsolete as there is zero reason I can see for mid/high end projects to start supporting eARC and therefore any projector + eARC only soundbar/receiver will hit this. It doesn’t seem far fetched that soundbars/low end receivers may follow the same pattern of single eARC hdmi for cost reduction as TVs with eARC start to become common.

What we want is the module that already exists in various TVs to do this, wrapped in a board & box. Two ports, one audio->eARC embed module, and a PSU if the 5v from HDMI is insufficient. That’s plenty for me as the audio/video split is taken care of already.

I’m sure the Sonos engineers would be able to give a great estimate of what’s needed, but I’m also sure they’re insanely busy at this point. I’ve reached out to a friend of mine to see if he’ll take it as a commission. Will see.

Example module - SiI9438 https://www.latticesemi.com/en/Products/ASSPs/HDMI21eARC 
The eval board is more than I want to pay, but the unit price on the actual chip should be more sane.

I am contemplating upgrading my Beam to Arc for the main TV and redeploying the Beam to the smaller TV.  I have my Beam mounted to the TV’s wall bracket using the Sonos Beam mount.  Whilst I see it is desirable to keep some distance between the Arc and TV but this is not possible in my case as it hangs over a fireplace recess.  How much would I be compromising the sound by mounting the Arc immediately under my TV and can the Arc mount be connected to my TV bracket to achieve this as per my Beam setup?

@snelld, the upward firing speakers might sound a little off if they’re clipped into the TV, but it shouldn’t be too bad. This might be a case where you just have to try it out and see how it goes. There’s a great money back guaranty you can take advantage of.  

Hey there,

@Ryan S

youmentioned earlier that there needs to be some space between the Arc and ceiling for the arc to reach the listener. My Playbar is currently mounted ca. 3ft 7in (110cm) under my ceiling because placing it under my tv on the board would block part of the TV screen. Using the same mount, would this be enough space or should I start looking for a higher stand for my TV?

Also, I am inclined to test it first before. During trueplay setup, will it indicate that the Arc needs to be placed lower in the room?

Thank you!

@Onkeldave, this depends on how far your seated position is going to be. Three and a half feet isn’t too bad, but imagine the audio has to bounce off the ceiling and hit where you’re sitting. Trueplay will help with that too, as much as it can. As above, this might be to test it out and see. Unfortunately I was incorrect about reusing the Playbar wall mount, the sizing was just too different and I was misinformed.

Hey there, I am an owner of numerous Sonos products plus a Sonos bridge but It been deactivated the last years , am I entitle for the trade in program and the 30% discount? I’m keen to purchase the arc, do you have any idea?

The 30% Trade Up credit can be applied to any Sonos product, including the new ones. The eligible products for getting a Trade Up credit are the old pre-2015 Connect and Connect:Amp, and the Play:5 gen 1. The Bridge is not eligible for this trade up credit.

Is a separate wall mounting bracket required for wall mounting?

Yes, there is a separate wall mount bracket, or you can use the Playbar wall mount if you have one.


I have a Playbar mounted on my wall and now interested in the Arc. Any insight if I unmount the Playbar will there be holes visible that the Arc won’t hide?

It was mentioned back a few pages that the Playbar all mount should work with Arc

Yes, but “should” and “will” are key distinctions when dealing with precise measurements/mounts, etc…  It would be helpful if Sonos could provide clarity around the interoperability of the two mounts. 

@BMF, @mkatz, @dssss, @melvimbe, and anyone else I might be missing, I checked in on this and I was incorrect. The Playbar wall mount is not compatible with the Arc, though from what I hear you can use the same drill holes when exchanging the mounts. Arc has a smaller footprint than Playbar, and while the team was trying to make it happen, they were unable to make it compatible. My apologies for getting this wrong. Arc is only compatible with the Arc wall mount available at: https://www.sonos.com/shop/wall-mount-for-arc.html

Any news about Atmos-support being rolled out to the Sonos AMP and/or Beam?

DD+ would be nice.

Wow.  I like it.


Given that it is eARC capable, does this mean that it supports the codecs Dolby Digital Plus and Dolby Digital TrueHD?  (Going to answer my own question from the product page)


Sonos Arc can connect to TVs with eARC, ARC, or optical outputs. For greatest compatibility, eARC is recommended.


If you connect to a TV with eARC, the Dolby audio formats supported include Dolby Atmos, TrueHD, MAT, Dolby Digital Plus, and Dolby Digital.


If you connect to a TV using ARC, the Dolby audio formats supported are dependent on your TV model and manufacturer. The TV may be capable of sending Dolby Atmos, Dolby Digital Plus, and Dolby Digital. An ARC connection cannot support TrueHD or MAT.


If you connect to a TV using the optical adapter, the Dolby audio formats supported are dependent on your TV model and manufacturer. The TV may be capable of sending Dolby Digital. An optical connection cannot support Dolby Atmos, TrueHD, MAT, or Dolby Digital Plus.

I too am disappointed by the lack of HDMI pass through, options etc. I have a 2019 Quantum TV with no eARC. I like my TV. We watch 90% of my content through our Apple TV. I am more than happy with my picture quality and don’t want a new TV. My wife would rightly be irritated since my ‘old’ tv was only 3 years old when I declared an upgrade necessary! I don’t need or want a new TV! 

I really, really, want a bigger more powerful sound bar than my beam. And I wanted Atmos. I was excited by the Arc. And now, seriously, one HDMI port. I can’t get Atmos from my ATV. And even if I could I want the MAX quality! Even if there was a way with a splitter or such its just a layer of complication that will irritate me when it’s quirky. 

I have Sonos because I like it’s relative simplicity. I don’t post much but when I do I’ve been accused of working for Sonos since I am generally very positive to Sonos. I like Sonos. I am just disappointed at the Arc and it’s lack of options. I wonder if we did a pole today how many of us have TV’s with eARC? By the time I get a new TV the Arc 2 may be out!

I am all for designing products that work for tomorrow, but make it practical today. I’ll stick with my beam, my SUB and play surrounds for now. And I will brood at my lack of Atmos as I walk around my house, and when my wife gives me the eye roll I will retort with ‘I know I know, 1st world problem, but COME ON SONOS!’. I really want more oomph and Atmos! I want to keep my house simple so I want SONOS to provide it for me!!

I was about to pre order one until I saw it won't work with the play:1s  I'm currently using as rears with my beam.  Quite disappointed since I only brought it as set around 9 months ago.

Could you point me to where you found this please?


It will work with Play:1s, Play:3s and Play:5 Gen 2.  The poster was mistaken.

The Arc looks like a great product. Great to see that Sonos has chosen to get with the program for Home Theater and include eARC and full Dolby codec support.

That said, unfortunately, I will not be ordering one soon. While not entirely unexpected, the lack of HDMI in/out in favor of eARC makes it impossible for me to implement. I own a projector, that I will not be replacing anytime soon, that doesn't even do ARC, let alone eARC. There aren't many TVs that have HDMI 2.1 with eARC yet and it's almost guaranteed it will take a few years for it to come to projectors - there is just no need, bandwidth-wise. For the time being consumer projectors are max. 4K and eARC is not that big of a deal since most people that project, use an A/V receiver.​​​


This is a good point.  Although you could utilize an optical connection through an extractor, you’re not get getting the full benefit of the product.  Hopefully, someone will come out with an extractor/splitter that  device that can convert HDMI into an hDMI-eARC signal at some point.

Great news about the ARC. Ordered mine today!  :hugging:  Selling one of my Playbars. 

Can’t justify upgrading my Play 5’s or Subs at this time.

IMO the audio “enhancements” for the Five don’t appear to be a game changer as they were for the Play 5 (Gen2) vs Play 5 (Gen1).  Besides my Play 5’s are bonded to a sub for low-end.

I’m not a bass-head with music and current subs do well with movies. I suspect the ARC coupled with the current Sub (gen1 or 2) and Sonos One’s or SL’s will be a great improvement overall.  At least that’s what I’ve told myself. :slight_smile:

Hello there. Yes the dolby atmos is shown in thr screen. Which i found very helpful. 

at first i was double checking everywhere. Incluiding in the area of the settings, bla bla bla. 
 Putting movies in 5.1 only. Others with atmos. Etc. 

and yes. Everytime its an atmos. It will display in the main screen. Obviously when u go to the other settings area u will see it as well. 

hope this is helpful. 

My Arc arrived yesterday and I can confirm that my 2016 LG B6 does not decode DD+ Atmos through it’s Arc port.  Needless to say I was kind of expecting it, but in the back of my mind I was hoping it still would. LG really screwed its 2016 customers over.  Here’s to hoping that an affordable eARC encoder comes out in the near future.  On a good note, the ARC sounds way better than my Playbar that I replaced. 

@Ryan S

Hi Ryan, 

Thinking of ordering the Arc when it’s available.

I still have a pretty old Sony TV. I am going to change it out but not right now.

Will the Arc function properly with my old Sony KDL52EX700?

It has an ARC HDMI port but not an e-ARC.

How can I set the Arc up for the best possible sound until I change for an e-ARC TV?


I use a bluray player connected to the TV for movies I own, but also stream to the TV from my computer.

Any suggestions?





I’ll give this a shot and try to make it generic and short. Please correct where wrong.

If your TV has ARC, can do compressed Atmos via DD+.


yes.  It should anyway, if the TV followed standards correctly.

If your TV has eARC, can do* “true” Atmos.



It wouldn’t call it ‘true’ as that would imply atmos over DD+ is fake, like it was system generated noise rather than what the producer intended.  Atmos over eARC, TrueHD, is uncompressed.  Semantics I guess


If your TV has neither, you can still do DD5.1 via optical or HDMI.

You can vis optical, but not HDMI.  The port on the Sonos Arc is not an HDMI input.

Assuming you have one of the first two above, connect the Sonos Arc to the ARC/eARC labeled HDMI port (HDMI #1 in the image above, on my tv it’s HDMI #2 on the side of the TV). Plug your other devices into any of the other HDMI ports as you normally would (in @Toffe example, connect the blue ray to HDMI #4 and computer to HDMI #2 [assuming that’s on the side] or whatever port is used for the computer).

* In order for Atmos to work, the original source will need to be sending the audio in the Atmos format. Additionally, your TV must be able to pass through the Atmos signal.


Like a lot of us I’ve been searching high and low for a magic box that will allow me to listen to Atmos from my ATV via my TVs ARC. (My TV is a Sony Af8). Anyway on another forum someone mentioned the thenaudio SHARC EARC audio converter. http://www.amazon.com/gp/aw/d/B083QPCNQN#Ask

I don’t know if it’s what’s required but from my limited understanding it might work? Could someone with more technical knowledge than me could look into it?

Well I am no expert on this stuff, so i definitely would not treat what I say here as reliable! But, the strapline for this device is:

“Converts TV EARC audio to a suitable format for your current sound system”.

So it seems to be designed for TVs with eARC working with sound systems that don’t support eARC.  Whereas anyone buying the Sonos Arc is likely to be in the opposite position.  Unless they have a very recent TV with eARC, in which case they are sorted anyway. No?

A review. https://9to5mac.com/2020/06/04/reviews-sonos-arc-atmos-soundbar/

I was about to pre order one until I saw it won't work with the play:1s  I'm currently using as rears with my beam.  Quite disappointed since I only brought it as set around 9 months ago.


Not so sure that is the case. Sonos mentions the One because this is essentially a sales announcement, and Play:1’s are no longer on sale.   The fact they say “a pair of our surround capable Sonos speakers, such as a pair of Sonos Ones” probably means the Play:1s will work, for they have always been surround capable.
