Home theater

I was thinking of installing acoustic panels on the walls to dampen some of the reverb in the room, but I’m afraid this will ruin the Dolby Atmos experience, given the Sonos Arc relies on being able to bounce sound off the walls and ceiling. Would this be the case? Any guidance on this would be appreciated.I have a Sons Arc, a Sub and in ceiling speakers as surrounds.

Hi,Have had a Sonos Beam, Sub (Gen 2) and Play:1s as surrounds for a couple of years. A couple of weeks ago I bought a Sonos Arc to replace the Beam.I have a 2016 Samsung UN65KS800DFXZA, with the following set up:HDMI1: Connected to DirecTV HDMI2: Commented to a Bluray player but honestly, its really not used HDMI3: Connected to Apple TV 4K HDMI4 (ARC): Connected to the Sonos Arc.On my DirecTV box I have the following set:Settings → Audio Settings → Dolby Audio → ON On the Samsung UN65KS800DFXZA I have the following set:Sound → Select Speaker → Receiver (HDMI) Sound → Expert Settings → HDMI Audio Format → BITSTREAM Sound → Expert Settings → Audio Format → Dolby DigitalThe DirecTV sound works fine..it’s awesome.Now on the Apple TV 4K I have the audio format set to:Change Format: OFF, so this sends LPCM to Sonos. I have also tried turning this

Dear support, I have LG OLED 55CXLRA, having a problem changing output from tv to anything other than Stereo PCM 2.0. My tv supports arc and hdmi is plugged into the correct socket. I’ve tried changing output type to Dolby digital, by default after initial setup it Dolby digital plus, however in the app it only shows PCM Stereo 2.0, after closing and reopenning the app or even re-connecting my tv. Please help!

Been there done that with everything I have read with other people submitting the same issue.  Newer top of the line router, speakers are 5 to 20 feet from Mesh router.  Still same, cutting in and out randomly. Have power cycled, removed the sub and added back in, have reset router (Power Cycle), always seems to come back.  Sometimes will go weeks or days with out the cut in/out.  But of course it always happens when you have friends over..lolI’ve read others with direct wiring with Ethernet cable and shutting off wifi to each speaker, and the issue is still there. Diagnostic report# 1676228203

I have a Philips Tv connected via hdmi to the sonos arc.  Works fine until the TV goes into standby then when it’s switched back on they forget to talk to each other. I have to turn off the TV and back on again to establish connection again. I’ve been through every setting on the TV and Sonos, however I’ve not found a fix. 

I just installed a Sonos system. It took me a while to get the Arc soundbar (with sub) and the two One SL speakers all connected. Once I turned the TV off and turned it on again, the One SL surround speakers are not producing any sound. The Sonos phone app is seeing them all together in TV Room and the lights on the One SL speakers are white. Any ideas?

I am using a sonos beam with two Ones for surround and a sub connected to my PC’s optical for 5.1. Anyway, the beam sits on my desk (elevated by a speaker stand). Sometimes I’m sitting down when I play games/listen to music, sometimes I put my desk into standing mode. So that means the beam can be either lower to the ground, like when I’m sitting, or higher up, like when I’m standing. Does it matter if I tune trueplay in either position? Would one be more optimal than the other? Should I maybe instead like set the desk height to be in between both for an average?  Also, I’m a bit loathe to walk around the room waving my iPhone. My floors creak. Also I’m never listening anywhere besides either my chair or standing up. Should I still wander the room even though the floors will creak and I won’t be listening at any other position? Thanks.

Here is one problem I noticed with my Arc + Sub + One system. The Arc connects with my LG C8 via HDMI cable to ARC. Every time I power on the TV, the sound switch back to “internal speaker + optical” audio option. I have to manually switch it back to ARC . However, after I am done this, the Netflix won’t show Atoms instead of showing 5.1 (the sonos app shows DDP 5.1). Then I will need to switch between internal speaker and ARC couple time, switch on and off for Dolby Atomos setting for internal speaker, reload Netflix couple time to get the Atomos sign back for Netflix and sonos app. Can I get some help with this issue? 

I have seen several posts of BEAM using HDMI ARC (in my case with a Samsung TV).Sound works for little bit and then cuts off.Fixes I usually see are unplug TV and Sonos and replug and try again. That does not fix it for me. I did see something about and update...but my BEAM is updated. I love Sonos...but this is killing me. I wonder if I am still within my return period.

Amazon music not working on Sonos Arc

I have two Sonos 5s, a Sonos one and a Beam. They are set up in a system.  The Beam is also connected to a TV. The Wi-fi system delivers a fast system … up to 200 mbps.  The Beam is very close to the router (within a foot)Every so often the beam drops out and the sound reverts to the tvAny thoughts or suggestions? 

Hi,I have 3 rooms with Sonos downstairs in my house (1 x Beam + 2 x One, 1 x One, 1 x Roam). The system itself always works fine, never had any drop out and Alexa always works. The app however constantly loses connection to the system and reconnects intermittently.I did discover recently however that if I go to the furthest corner upstairs the app connects instantly and is stable.I have tried the standard off/on again on my router and every Sonos device, but no difference. I also tried the app on IOS and android devices and it is the same on both.I don’t have anything obvious that would be interfering with the signal downstairs, and as it’s the app not the Sonos system that is cutting out I’m at a loss! It does seem to have got worse since I purchased the Roam.Any suggestions appreciated! Cheers.

Hi there.Quick question with regards to the Beam wall mount… once the Beam has been attached is it flush to the wall, or is there a gap so as to allow cables/trunking to run behind?I’ve searched as there’s nothing obvious, so apologies in-advance if this has already been asked and answered.Many thanks, Mark :-)

Hello,I recently bought a Sonos beam in which I have it connected to an LG 4K tv thru HDMI (ARC). Every time I go to watch tv and have the audio play through the beam - it’s fine. When I want to switch over to music my beam gets disconnected from the APP in which I have to do the “let’s fix this” steps. Anyone have any ideas how to fix this and seemingly switch from TV audio to music? The Beam is connected via WIFI. I have the TV autoplay set to off. TV audio always works, just playing music bugs it out for some reason. 

I’d like to setup a soundbar in my house and I really like the look and specs of the Sonos Arc but I’m not interested in any connected features.  I just want the sound out from my TV.  Can the unit be operated without any network connection at all?

Hi, my diagnostic number is 179484943.The audio from my tv works fine sometimes and others it cuts out all the time, regardless of the channel.  Two paired Play 1 speakers with a connect hardwired to the tv and router.  Both speakers show WM:0.Any help would be much appreciated.

Ok. I’ve seen many old posts regarding random soft bong sound coming from Arc. Keeping it simple… my Arc has never been connected to my TV. I use the Eero Pro WiFi that has performed extremely well. I use Alexa only on my Sonos devices. Sound tone happens when not using Sonos for 24 hrs. Seems like real issue that has not adequately been addressed by Sonos. I’m regretting my $2k purchase and afraid to mount this device. Please help. B

Hi hopefully you can help...I've been having trouble using my Sonos system recently.The Arc disappears from the Sonos system after playing music in a group with other speakers from Spotify.When I group the Arc (with sub and 2 rear surrounds) with a Sonos One and Sonos Five,  it fairly consistently drops out of the system, requiring a power cycle to bring it back. All speakers are connected by WiFi. All except the Arc are using 5ghz, not sure if this is relevant...My wifi router is an Asus RT-AX55. I had a search and found an article suggesting disabling a setting (airtime fairness),  but this doesn't appear in my router config.I've tried connecting an Ethernet cable to the sub and use SonosNet but this didn't work at all. Nothing could connect, I assume its because it is part of the Arc subsystem… Any ideas on how I can fix this for good? Thanks,Paul

Suddenly I am hearing my Beam bass is distorted with a vibrating noise. I have been using the factory set equalizer setting without any custom adjustments.

I have the black subwoofer that has the single button on the front.  When I plug it in no lights or anything appears on the front.  I have tried another power cord, tried holding the button on the front and plugging it in.  Nothing works.  1k for a few years…  do you have any ideas?

I have a Sonos system hooked to my TV. A Playbar, two Play 1s, and a sub. My issue is, I think the sub may be missing some lows. It hits incredibly well, but there are movie parts that I remember being so much better on my traditional sub than on the Sonos sub. A clear example is the Lion King. When all of the animals are coming to Simba’s introduction at the beginning, the traditional sub would shake the house with the elephant steps, but the Sonos sub barely even plays those steps. I don’t know if it’s part of the remastering of the movie, or a lack on the part of the Sonos sub. If it’s the latter, is there a way to make it pick up and play those sounds? As I said, it is great in most movies, but maybe I’m missing something I don’t realize because I’ve only ever seen those movies since my Sonos system. 

I plan to fix my Beam under my 24” Panasonic Tv (vesa 20x10) which I plan to change to a 32” later this year.the TV is on a fixed Spectrum PL60 floor stand and the vesa bolt holes are 19cm and 29cm above the lower edge of the tv.So, I’m looking for a simple solution that would have 2 vertical L shaped brackets that would be at least 30cm long to allow fixing, space for the Beam and access to the controls.Spectrum say it can’t be done, but I believe there must be a simple solution out there. Does anyone have any recommendations? thanks

Hello everyone.I have a wall-mounted Arc and find that for many movies/shows, the sounds are quite loud, but voices are too quiet.  My kids are watching cartoons now, and the sounds (crashes, sound effects, etc.) are BOOMING, but the voices are quite lower in the mix. - Loudness:  OFF - Trueplay:  ONIs anyone else running into this?

We cannot get our sonos system working with our android phones. We have 2x sonos one sl speakers, and we were looking to expand, but we can not connect to our sonos system from our android phones. We daily reset our router, restore to factor settings on sonos speakers, but after the initial setup on connecting the speakers to our system, we loose connection, and the sonos app cannot find our system and speakers. We have tried everything from reinstalling sonos app, reset ting our router, factory settings on speakers, and yes the speakers and phones are on the same stable WiFi with maximum signal. We have No option for wired settings. This issue with No detection to sonos system from the app is extremly frustration. Anyone Who could help? Ty in advance This has lasted for two months now.
