Arc Ultra and Era 100’s  Anyone else have this setup and noticing that the Era 100’s as rears are doing less work with the Arc Ultra when compared to the standard Arc? I’m barely noticing any audio coming from the rears even with the surround volume turned up to maximum.  I swapped my original Arc back with the Era 100 surrounds and tested the same Atmos movies on the Arc and the Arc Ultra, and there is a significant difference/reduction in the signals being sent to the Era 100’s in the rear channels with the Arc Ultra.  Increasing the “TV Level” setting for Surround Audio in the Sonos app increases the front surround volume coming from the Arc Ultra but the signals coming out of the ERA 100 rears are almost non existent.  Is this behavior the result of how the Arc Ultra processes surround channels, and should be considered normal operation?

Hi allI thought I would start a thread about this since there are a lot of people with this issue looking for answers. There is currently an issue with the Asus firmware and Sonos devices set up in Home Theatre mode where Guest Network Pro has been activated on the router. For my setup it is the Arc paired with a Sub and Two ERA 300’s; however, many other setups also seem to be affected. Here is a long thread which I have been running where the process has been documented. Today Asus provided me with a Beta firmware which seems to have solved the issue. They are looking for users to test is, such if you would like to test it and provide me with feedback please reach out on the SNB forums. I submitted this to Sonos a number of times; however, they have not done anything about it. Thank youRemi

G’day from Australia,New to forum here, so apologies if this has been covered elsewhere.I have recently invested in Sonos Era 1 speakers, Sub Mini to go with existing Beam Gen 1 setup.I want to use the the setup for both music and home theatre, so currently music utilises the Era 100’s and the Sub, which is fine for my needs at present. However, as the Tv is only connected to the Beam, do I always have to reconfigure the Era speakers and sub, if I want to use them for the Home Theatre set-up.Or can I just create different rooms, even though they are all part of a 5.1 system in reality?Hope this makes sense!Cheers

I have two  Sono​​​s sound bars a Ray and ​​​​Beam V2 and I understand the Ray has limited audio options and is showing Dolby Digital 5.1. What I’d like to understand is what formats should be showing for my Beam v2 and what's the best option?I think I used to see Dolby Atmos when using my Netflix Premium account which I no longer have so not expecting to see this any more.It is showing Dolby Multichannel PCM 5.1 is PCM good or bad I’m sure I’ve seen Dolby Digital Multichannel 5.1. or Dolby Digital Plus 5.1. So which is the best option Dolby Digital Plus 5.1, Dolby Multichannel 5.1 or Dolby Multichannel PCM 5.1I was trying to test Atmos using Youtube test clips but Dolby Atmos was never displayed. The formats listed by Sonos do not tally with what is shown in the app:Dolby Digital Plus Dolby Atmos (Dolby Digital Plus) Dolby Atmos* Dolby TrueHD* Dolby Atmos (True HD)* Multichannel PCM* Dolby Multichannel PCM*TV in question is Samsung connected using HDMI Arc & Digital

Just learned about setting up a surround sound system in my basement. I have an arc ultra at the tv, 2 era300s front L&R of TV, sub gen4, and amp with 2 sonance celling speakers as R&L rear surrounds is there a better configuration to take full advantage of Dolby atmos or surround sound setup in general? 

I’m unable to connect my beam gen 2 to the Mi Laser Projector 150. I’ve tried connecting the beam gen 2 to the projector’s HDMI 3 (ARC) port but it’s still not working.  Anyone has encountered this issue before?

Hello, after using TruePlay my rear speakers are really loud and greatly over power the front (Arc Ultra). They are only 6” away if I sit on one side of the couch, around 2’ if I sit center (they are in a console table right behind my couch). I know that “Surround Distance” is grayed out after running TruePlay. Am I really just better off not using TruePlay and just setting surround distance to “Less Than 2ft”? Just bummed that I have to sacrifice the TruePlay EQ because it doesn’t reduce the rear surrounds enough.

I’ve got a Samsung smart monitor with an HDMI-Arc port connected to my Amp. I can get the TV connected via the app and I hear the chime, but no TV audio plays through the speakers. Line-In and regular music play fine. I’m using a very long 50’ HDMI cable because of my room configuration (been buying from Amazon to test and return if needed). This has been my second attempt with a similar cable. I read somewhere that 8K cables don’t send the same signals as lower rez-rated cables. These all have crazy name/ratings like “HDMI 2.1 Cable 50ft White 4K 8K Fiber Optic HDMI Cable [8K@60Hz 4K@120Hz, 48Gbps, Dynamic HDR, HDCP 2.2&2.3, 3D] Compatible with 4090, RX 7900 XTX, Monitor, PS5, Soundbar”. Also read that the length could be the culprit.Anynet+ (HDMI-CEC) is enabled. The cable says it is directional and I’ve switched both ends but still no change.Has anyone encountered a similar situation, either connection chime but no audio, or figured out getting proper sound while running a long

I have installed a new Ray with two Play 1 surround speakers and paired the Samsung TV remote and all is working well including the remote volume control. But I have a question that relates to the remote and powering off the Sonos system.Does the Ray have the power on and off functionality and if it does should it power off when switching off the TV, if it should how is this configured ?

I have move and have a new internet source how do I update my system to accept the new internet. It will not recognize my app. 

I have a LG oled48c44la TV which has a wired connection to a Sonos Beam working successfully.  I want to add 2 Sonos era 100 speakers to use as satellites, but they cannot be connected by wire.  Is there a way to play through the wired Beam connection and at the same time play wirelessly through the era 100s?

Problem:Almost daily, my surrounds/sub all disconnect from the Arc Ultra and stop playing sound (thought he Arc continues working as expected). When this occurs, the app shows "Needs attention" for the Arc Ultra. Power cycling the Arc Ultra immediately resolves the problem for 24-48 hours.Setup: Soundbar: Arc Ultra (connected via Wi-fi) Surrounds: 2x Symfonisk Bookshelf Gen 2 surrounds Sub: Sub Mini Routers: Asus AX86U Pro + AX58U AiMesh Node Other Sonos speakers in the house use SonosNet via a single Symfonisk lamp that is wired to the router (does SonosNet play any part for the surrounds/sub in this setup?) Things I've Already Tried: Various AiMesh binding options Disabling DFS channels on 5 GHz Setting router 5 GHz control channel to static value Disabling automatic Sonos firmware updates (on the theory that the update process resulted in the disconnect) All the standard Asus Wi-fi tweaks to improve compatibility with Sonos (Airtime Fairness, beamforming, etc.) Rep

I just bought the Sonos Beam Gen2 in December of 2025 and have it connected to my Samsung TV that I bought 5 years ago.  I went through the setup procedure and the sound quality is very poor especially from my Samsung Blu Ray player.  I used the HDMI cable that came with the Beam and it’s connected to the ARC connection on the TV.  I have to turn the volume on the Beam to over 50 so I can hear and understand what they’re saying especially on the Blu Ray player.  

I have an Arc Ultra and a Sub 4.  Currently, the Arc Ultra is connected to the internet via a switch, and the Sub 4 is connected via Wi-Fi. I would like to hardwire the connection to the Sub 4.  Is it just a matter of connecting an ethernet cable from the switch to the Sub 4?  Are there any other steps I must take to complete the conversion? 

Hello everyone, I just installed 4 sonos amps in my new house and on one of these I connected the hdmi arc cable to listen to the tv with the sonos system, now I would need to send the arc signal to all the other 3 amps to listen to the TV audio throughout the house. How do you think I can realise this?Thanks to those who will help me or give me some advice, I'm new to the sonos world 

My arc ultra is connected to my Samsung TV by ehdmi and works fine. I can set up my Era300s (2) as stand alone speakers but when I set them up as surround with my arc ultra it shows connection issues with the eras. Any advice would be greatly appreciated. 

System info:Sony 77 A80J TV Apple TV4K (connected to Sony TV via HDMI 4) Sonos Arc Ultra (connected to Sony TV via HDMI 3 eArc)Issue: Turn system on (usually via Apple remote) after everything being off overnight or some period of time and sometimes Sony TV immediately will be using the external audio which is the Sonos Arc Ultra and sometimes I’ll find the Sony TV will be using the internal TV speakers and I have to manually switch TV audio source to the external audio source (Sonos Arc Ultra). Question: Anyone know what causes this erratic behavior and how to fix it so the audio is consistently external audio of the Arc Ultra?

Don’t buy sonos, is terrible in every posible way Moderator edit: Corrected “Sony” to “Don’t” for clarity.

Im noticing that as time goes on the volume has to be raised with everything I watch.

Hi, I had issue with playbar : whistling noise coming from power supply unit -  transformator. I have used epoxy resin to cover it up and noise is barely hearable. epoxy flowed a bit to a diode and surrounding components just 2cm not more ( would this cause issues?) However : after this I connected it all again and I bass lavel is very low. void this be because of psu fault ? Resin on pcb ? I connected all speakers correctly . all speakers vibrate and works but I can’t hear enough bass . please help ! 

Am i being petty regarding my Sonos Arc Ultra having it grill holes not aligned? Moderator Edit: Corrected “pity” to “petty”.

Hi everyone, I’m trying to set up a home karaoke system and I’d really like to use my existing Sonos setup, rather than buying a separate karaoke speaker (JBL, etc.). Here’s my current setup: Sonos Beam (Gen 2) connected via HDMI ARC Sonos Sub Two Sonos surround speakers Source: Apple TV (YouTube karaoke videos)  What I would like to achieve: Use one or two microphones Hear the microphone voice through my Sonos speakers At the same time as the music coming from YouTube on Apple TV Ideally with minimal latency  I understand that HDMI ARC is mainly designed as an audio output, not an input, which makes this tricky. My questions: Is it technically possible to inject microphone audio into a Sonos system like mine? Would a mixing console help, and if so, what would the correct signal chain be? Is there any workaround (HDMI audio mixer, extractor, etc.) that could work with Sonos Beam Gen 2? Or is this simply not feasible with Sonos home theater products?  I’m open to external hardware if ne

Does anyone know how to connect the beam gen 2 andini sub to the Hisense tv hi concerto feature so all the tv speakers and Sonos can work together.

My Arc Ultra and Era 100’s sound like an AM radio.Shallow, tinny, no presence. Wasted money but my Wife likes the voice command and whole house soundDo I add a subwoofer or replace the 100’s with 300’s?

I won't buy sonos in the future they make it outdated so you keep buying there setup very annoyed. Anyone found a decent remote
