Home theater

I have a new Arc Ultra paired with an amp that has four in ceiling speakers and am also using a wired Polk Sub that I had.  Whenever I change the Arc to use “Surrounds” the sub woofer doesn’t work.  The only way I can get it all to work at the same time is to keep them separated and turn the volumes up for both.  That creates a bit of an odd echo though and isn’t really surround.  Any thoughts on what I’m doing wrong?

Looking at purchasing the Sonos Arc Ultra (and sub and rears), but been doing some investigation on how to connect the ARC to a Samsung TV via the One Connect Box … and could not really find much.  The ARC Ultra will be to replace my ageing Denon Amp and speakersMy Samsung One Connect Box, currently has the SkyQ box and another device connected to it … and then via the “one connect” cable .. runs to the TV.  There is also an Optical Cable connecting the Amp to the One Connect BoxSeeing as the ARC Ultra only has one HDMI port… how would this work with the One Connect Box …. would I just leave the the SkyQ and other HDMI device in the One Connect box … and plug the ARC Ultra into the One Connect Box?Thought a little diagram would help.  The red (ARC Ultra) is what I want to add  

So I have  2 (surround) speakers connected to an AMP.The AMP is placed far away from the setup (basement), so there is no way to do wireless, and everything is wired.I have no soundbar yet… but are considering buying one… So my question is is it possible to use this AMP (that is only accessible by ethernet and not wireless) as surround for the Arc Ultra?

Hello, I just purchased (May 2025) a Sonos Move 2 speaker. Indeed superb!!! Connects fine to the current Sonos app. But the app will NOT find my Sonos Beam Gen 2 soundbar. I checked the Wi-Fi settings, all OK. I believe I read somewhere about the Gen 2 Beam not being compatible with the latest Sonos app. My router is an Eero 6, and on the Eero app it does show the Beam as connected at 2.4 GHz which is the right frequency. The Move 2 uses 5G. Would appreciate any advice. 

I have an existing Sonos system that worked fine with my older Samsung TV.   I recently replaced the TV with another Samsung.   When I try to use the optical connection (one end in the TV and the other into the soundbar as with the other TV), all I get is chattering with nothing intelligible.  It doesn't matter if it is DISH, Netflix or Amazon.  Shouldn't it just work by plugging it in the same way? 

Hi, I have a question. I purchased an Arc Ultra Era 300 and an Era 300 Sub 4 a few days ago and I connected them together as surround sound, but I realized that if I put songs that don't support Dolby Atmos/Digital on, the Era 300 doesn't work, only the Arc Ultra works. Is it right to be concerned?

BEAM reset to factory settings and then go thru the add component optionsCompletes and get the message below - no Beam anywhere after unplugging - nothing to do in system Settings either.

Since the last update, trueplay process isn't saved in the end (see the picture, i can't toggle trueplay on or off after process) i tried on iOS and android, same issueArc ultra + sub gen 2+ era 100 

I recently replaced my Sony with a Samsung S95D. Now the Sonos Arc will show it is connected, but no sound comes out. I have tried multiple HDMI cables, and it lasts a couple days, then the sound becomes choppy and then no sound. I have called Samsung as they state since the sound bar shows it is connected, it is a Sonos issue. I have reset the Sonos soundbar, reinstalled, reset the tv, and there are no other HDMI sources connected to the TV.  HDMI e-Arc is turned offTried Digital Output Audio set to Auto and PCMReset External Device Manager Anynet+ (HDMI-CEC) to off and on.Sonos ARC has up to date firmware Version 17.0 (build 85.0-64200)I am at a loss. 

I’m a newbie and so apologies if this has been covered- my survey didn’t turn up an answer.  I have a Yamaha RX-A870 (7.2?) with 4 Klipsch wired speakers-  left, right, center and sub.  I have two Sonos 1 speakers and I would like to use them for the rear surrounds.  I also have two sonos connects.  Can someone help me with a set-up?thank you

So, for the past 3/4 years. I have had the ARC and sub working flawlessly with my older non-4k Samsung TV. It had a Direct TV Stream box and Apple TV. Here is how it was connected:ARC to TV-  HDMI to optical out using the Sonos dongle Direct TV Stream to TV-  HDMIApple TV to TV-   HDMIVolume was controlled with either remote(Direct TV or Apple TV remotes) and you would see the ARC respond to any volume changes via the lights on the front of the ARC. The TV would show that it was using external speakers.OK, everything worked great. Now here comes the issue.I get a new Sony Bravia 4k TV and did a basic swap. The only thing I changed during the swap was I removed the HDMI to Optical dongle and went straight to the HDMI/ARC port on the TV. Now it nothing comes out of the ARC. I even swapped tt with a newer ARC just in case it was stuck on the old settings but it still didnt work. Here is my setup:TV:   Sony Bravia XR-77A80KApple TV hardware:What am I missing to make this work? On a side no

Which subs are compatiable with Arc Ultra?Sub mini, Sub 3 or Sub 4. Which speakers are compatiable with Arc Ultra?

Hi!Im about to build my own home cinema, but i have a question.Im bying a projector screen that is mounted in the ceiling, and a tv on the wall, so i will connect the Sonos Arc Ultra to the Tv and Projector at the same time. Is it possible to conect the Arc to the TV with the optical input, and the HDMI Earc to the projector?I know that the optical input only can deliver 5.1, and the projector will have HDMI earc for the full ATMOS. Thanks! 

I’ve seen this issue discussed on various forums and across the internet, but no real solution has been provided to the users. Configuration: Arc Ultra + 2 Era 300 + Sub Gen 4 When I switch off the Sub Gen 4, the bass becomes much more present and dynamic—it really pops out of the mix. However, with the sub enabled, the bass in the 80Hz–40Hz range sounds muffled and recessed. Try playing Fast Car by Tracy Chapman in high resolution. It’s very noticeable: with the Sub Gen 4 disabled, the bass sound is clear and well rounded, but when the sub is active, it loses clarity, body and impact. I’ve already experimented with Trueplay (on both Android and iOS), sub volume, sub phase, and EQ settings. The issue persists and seems to be related to a crossover problem between the Arc Ultra and the Sub. Best regards Federico

Bonjour à tous, je rencontre un problème récurrent de décalage de son vs image lorsque je regarde la TV en direct en UHD.  ma configuration: - décodeur TV sosh relié à TV connectée Samsung (modèle de 2019) via HDMI - TV connectée à la  barre de son sonos ARC ultra depuis port HDMI ARC via câble HDMi sonos d’origine.  problematique: - décalage de son par rapport à l’image lorsque je regarde la TV diffusée en direct en UHD. -pas de décalage de son si je déconnecte la barre de son de la TV et que j’utilise les hauts parleurs de la TV -pas de décalage de son non plus si je regarde du contenu UHD en replay ou sur plateforme de streaming en différé. La problématique ne concerne que les flux UHD en direct.  Auriez vous une idée de la provenance du problème et comment on pourrait le résoudre ?  en vous remerciant d’avance   

Hello, new to Sonos speakers and I love how clean they look in the living room. I do value accuracy with my home theater TV/Speakers. I have two Era 100’s as surrounds on a console table behind the couch with a Beam/Sub Mini and just curious how to angle them or how to properly set them up.I currently have them pointed straight to the TV but depending on where I’m sitting on the couch they can be pretty loud. Especially with stereo content playing music with speaking as music seems to go to rears. I have used TruePlay to get them started and after I was able to reduce TV Surround to -3 which matches other speakers with my dB meter. After running TruePlay the surrounds say they are more than 10ft which i know is not accurate and the only way to change that is by turning TruePlay Off. When I turn it back On it defaults back to more than 10ft.Any suggestions? Is it better to run without TruePlay? Are we able to have rear speakers off when Stereo content is present and only play in front,

My Samsung Frame TV is connected to my Sonos Beam (Gen 1) via an HDMI-ARC connection in the Samsung OneConnect box. I subscribe to a variety of streaming services (Netflix, Prime, ...). All my Sonos audio sources, and all the streaming services play at a normal volume. However, when I am watching live TV, max volume is about 20% of the other sources. When I look at the volume slider through the Sonos app, when TV is playing, the slider is at 100 and barely audible (whereas with my other sources, the slider is rarely above 30%). How do I boost the TV volume?

I have recently got Sonos Arc Ultra. So does adding one Sonos Era 300 as surrround speaker would be good enough or need to add 2 . 

Hello - I’ve set up my Arc Ultra with 2 Era 300s as surround speakers and a sub 4. Everything is aligned from a home theater perspective in the app but I can’t get TruePlay to work.  I go through the steps and it plays all the test tones but then I get an error message as shown below. I’ve tried deleting and reinstalling the app with no success. Have tried it multiple times and still get same error. Using my iPhone 16 Pro.  Any suggestions on how to fix? thank you  

My Gen 2 Sub worked fine with the old Playbase and still works when I pair it with my Play5’s.  I can pair it with the new Arc Ultra but it doesn’t work after pairing.  It shows up in the Arc setup along with the Era300 surrounds.  I can make adjustments to the sub volume but nothing works.It’s interesting that turning the sub switch off in the Arc group improves the bass.  I’m guessing when the switch is turned on the Arc turns down it’s bass.Sonos says they support the Sub gen2 with the Arc Ultra.  I’ve disjoined and rejoined to no avial.

Hey y'all, I've had a gen 2 beam for a while now, today I picked up two era 100 pros, if I set the eras into surround sound I get zero sound at all from them, I can not even play music through the surrounds.  Beam works great, I'm beating my head against the wall trying to figure out why I can't get any sound at all.  I have the music part of it set to "full" and eras were fully setup in their respective "rooms" until I created surrounds with my beam.  What am I doing wrong that I get zero sound from the surrounds.  For the record I can turn up the volume on my beam from the era 100s even pause music play, just no actual audio ever through them.

Hi there, a really annoying problem: Got my Arc Ultra set up, eArc to HDMI, 2 Era 300 as rears and planning on buying a Sub 4 once the pain in my purse goes away.There are 2 content suppliers connected to the TV, an LG OLED65CS9LA: an Apple TV (latest model) and a PS5. Problem is with BOTH of those so it’s either the TV or the Arc. What happens is that after it was off for a few hours - like over the night - the system will only put out Stereo PCM. I have to manually change the sound mode in the TV settings (anything will work as long as I change it, auto, passthrough, no matter). All the other settings are correct, it’s just as if, when off for a few hours, the TV forgets to tell the Arc that it sends surround sound & me changing stuff will remind it.I read that it might be a problem with cheapo HDMI cables so I bought an expensive one and a super expensive one and nothing changed.I am very annoyed and would be extremely grateful for a solution.

Hi,I just purchased a new Arc Ultra and LG G5 OLED 65”. I have connected the Ultra to the eARC HDMI (2) of the TV using the supplied cable. On setup using the app, I received the message, “A device is interfering with the HDMI connection. Disconnect any other home theater products, then try again.” I have 2 other devices attached by HDMI, a Virgin cable box and an Xbox One. I removed all other HDMI devices and tried again but still received an error on setup telling me it can’t find eARC this time.The Ultra is, however, playing sound from all of the sources that I ask it to despite the TV setup failing every time. I’ve tried power cycling, ensuring Simplink is on, etc. but just can’t get it to complete setup.  It’s incredibly frustrating. Any advice would be greatly appreciated. 

I have a Sonos Beam paired with two Sonos One SL (2nd gen) speakers as a home cinema setup, and I’m really happy with the sound quality. Since I’m such a fan of Sonos, I recently added a Sonos Era 100 in the kitchen.The issue I’m running into is this: after playing music throughout the house (including the kitchen), when I switch to watching TV, the TV audio also plays through the kitchen speaker. To fix this, I have to grab my phone or iPad and manually remove the tv sound from the kitchen speaker.I understand how grouping works in the Sonos app, but I’m wondering:Is there a way to automate which speakers are used for TV audio versus music playback?Or is manually adjusting the group via the app the only solution?
