Home theater

System is as follows: LG OLED65C8PUA Sonos Arc 5.1 w/sub and two Sonos One-SL Tivo, Apple TV, Blu-Ray Player I have had my Arc system for a few days. At various times, the audio cuts out and the TV’s internal speakers take over.  After a few seconds, the Sonos white light starts flashing and eventually, switches back to the HDMI-ARC restoring full audio.  I have tried several cables and still experience the problem.  The last time it happened, I submitted diagnostics: 444199566.   Any help would be greatly appreciated.

Hello,  I wonder if the function to swap left and right speaker of the Beam/Soundbar could be an option to have in future updates of the Sonos app?  I've seen some topics about it, but all closed and no official announcement about it.   Owning a video projector, this function, would help a lot for having good configuration, allowing upside down mounting on the ceiling or even having the beam in the back, behind the sofa…   Don't you agree?   Thanks! 

I have a Playbar and I am using two Sonos/Ikea Symphonisk speakers for surround sound speakers. I am looking to add a Sonos Subwoofer to complete the system. Would the sound be any different/more superior with a Gen 3 vs a Gen 2 subwoofer?

Hi there. Complete Sonos newbie and hoping someone can help… I installed my new set up over the weekend, comprising Sonos Arc + sub (gen3) + 2x One SLs as surrounds. Initially, I had all four components set up wirelessly over my home network and everything working great. I then did some reading over the weekend about SonosNet (tbh, wasn’t even aware of it ;). The Arc and Sub are both within easy reach of a gigabit switch so these are now connected via ethernet. Under ‘About my system’ the Arc and Sub both show WM:0. I also disabled Wi-Fi for both and noticed that SonosNet channel was now enabled under Network (had auto-selected channel 6). OK, now I’m getting to it… My expectation was that the two One SLs (surrounds) would now be connected wirelessly by SonosNet rather than via my home network. I checked under About my system, and they both showed as WM:1 (I was also able to confirm that they were still wierlessly connected to my router). I unplugged the two One SLs overnight but

Just connected Beam Soundbar and two One SL speakers to TV. Connection was successful on app. The Beam plays from the TV and the One SL speakers can control Beam sound so I know they are connected but One SL speakers do not play sound. The Beam is connected to TV by Arc cable and the One SL speakers appear to be connected to my WIFI and must be bc they can control Beam sound.

So I finally received my Sonos Arc and One SLs  today.  Unfortunately, I will not get the sub for a couple of weeks.   As a first time Sonos owner, the setup was super easy And uneventful connecting the Arc and Ones together.     I have an LG OLED B8 series TV with AppleTV  4K.  I mention this because I do not have eARC, so I do not get true Dolby Atmos (DA).  But I have noticed that plugging the Arc sound-bar into the HDMI ARC does NOT sound as good as plugging it into the optical and changing the the TV output to internal TV speakers + optical with DA and adaptive sound turned on.  I believe the is the lossy DA I have read about (basically Dolby digital+).   It is nice!   I do look forward to hearing true lossless DA at some point.     I have spent the past few hours on YouTube (with Apple TV in the HDMI ARC) and looking and listening to DA tests, samples, movie trailers and frequency tests.  As most have probably heard about the bass issues, yes I notice it and duplicate it.

Hi all,   I have a surround setup with an Arc connected to a Samsung Q900RA (2018) through HDMI (channel 3: ARC), two Play Ones as rear speakers and one Sub (2nd gen). The Sub is connected to our network by Ethernet cable and is located no more than 5 meters away from all of the devices in this setup. I also have a couple of other Play Ones and one Play:5 scattered throughout the house.    Previously I had a Playbar connected through optical. I’ve had the Arc since release and had no problems up until a few days ago. Occasionally the sound (Internal TV apps as well as external devices) starts to drop-out for 1 second, every 10-15 seconds. Reconnecting power seems to help for a while but the problem reappears at least once a day.    Other devices I have connected are a PS4 and a Nvidia Shield TV. As I purchased the Shield TV a few days ago I figured it must have been some CEC (aant er) interference, but the problem does not go away if I disconnect the Shield TV entirely. I’ve also

I need help. I’m trying to find a Blu-Ray player with a separate HDMI audio output that I can run directly into the Arc. That will give me Dolby Atmos. I know it sounds simple, but I can’t seem to find one that does the job. Any advice? Anyone running a similar setup that works?  Im running an LG HU70LA projector, and it won’t pass through Dolby Atmos, so I’m hoping a second Blu-Ray audio HDMI directly into the Arc as a workaround will work. Unfortunately, so far Panasonic Blu-Ray players give me no audio when wired directly into the Arc with the audio HDMI. Update: it appears that Sony does not work either when wired directly into the Arc many thanks in advance

Hi All, The Sonos Arc is not "opening" the HDMI ARC port on my TV properly and I need to do it manually each time. In other words, when I turn the TV on via the Apple TV (or TV directly), I manually need to press “input” on the TV remote and click on the HDMI arc port (and see the Sonos splash screen) before the sound starts to come through the Arc instead of the TV speakers. This is really annoying and I previously had the Beam which didn’t have this issue, so it definitely isn’t the TV. My TV is a 2016 LG 4K OLED (OLED55B6T-T)   Sonos Product management, could you please add this to your list of things to fix?   Regards, James    

How much space do you need to leave off the end of the arc.  Considering having it built in a bit to a wall.  Thanks. 

We have a bar and two speakers. My husband is fairly deaf. I'd like to turn up the two rear speakers so he can hear properly (they are either side of his chair) without making the bar volume higher as currently it's too loud for the rest of the family. Is there a way to set this up please?

Hello. I have a home theater set up with Playbar, two Play:1 surrounds and a sub. Suddenly today, my TV does not appear to be outputting any sound to my home theater. I’ve done all the usual checks (optical cable/red light; TV sound settings; Dolby and not Dolby Plus; etc.).  Not that this matters, but I’ve checked my TiVo, Apple TV, and the TV directly to see if any sound passes through and it does not. All boxes are connected via HDMI to my TV; the TV is supposed to pass sound through the optical cable.  That everything was working fine for two years and then suddenly stops working is very strange. I’m not sure what worse I can do to fix this. Please help. I have a SONY Bravia 75” 4K OLED TV if that helps.    Diagnostic: 1619880235.   thanks! Jay

So I have the ATV 4K (using the Infuse Pro app), LG C9 connected via ARC port (enabled eARC) with the Sonos Arc + HT (Sub Gen2 + OneSL) I have a source file playing with Dolby TrueHD 7.1 track but I am only receiving DD 5.1 on the Sonos system as verified by On the App.  Is this normal ? Shouldn’t I be or supposedly be getting Atmos sound on the Arc Home Theatre?    Netflix, Disney+, and Dolby Atmos test files (playing from Infuse Pro App) are working fine with Atmos though. 

I’m interested in getting an Arc. I’d also be getting a new TV, and so can make sure it has the right features. Even so, some discussions about surround sound support give me pause. There doesn’t seem to be one definitive explanation for all this, so here’s my best attempt, as someone who hasn’t typically paid much attention to different surround sound formats, and who is new to Sonos products. Please let me know if I’m understanding correctly, and if there’s anything I’ve gotten wrong. In a traditional HDMI-centered setup, various devices send digital AV signals to a receiver, which decodes the audio to analog for its speakers, and passes on the video to a TV. Each device has its own preferred digital audio output format; the receiver supports most every kind of signal—various Dolby formats, DTS formats, and raw PCM. The Sonos Arc uses a different model: all digital audio signals come from the TV via its ARC HDMI output. Other devices send their signals to the TV. Three limitations:

Word of warning for anyone looking at the Beam to start a 5.1 surround sound system, it will NOT work ideally for any streaming box except the Apple TV. I would suggest really doing your research and/or staying away from the Beam if you want a home theater solution. The Beam does not support Dolby Digital Plus (DD+) and only supports PCM (poor quality) or Dolby Digital. Why does that matter? DD+ is the current standard. Dolby (the only thing Sonos support) sounds good but is hardly used anymore by anything halfway modern. PCM is the audio equivilent to standard definition TV. DD+ is the de facto standard for streaming boxes and services. Hulu, Netflix, HBO and I want to say Plex support this standard and only this standard. Those services do not use Dolby Digital. To get Dolby Digital, that means the stream must be downconverted (transcoded) on the fly by either your streaming device or your TV before reaching the Beam. If you do not convert, you are forced to use the poor qual

Hi Have connected SONOS AMP to LG 9C TV using brand new High speed HDMI cable via eARC port in TV. Works fine : SONOS AMP receive TV sound through HDMI eARC and plays it in loudspeakers and in other SONOS speakers in my home. During the day I use same AMP to play streamed radio or music - also in the entire home - this also works fine. When it’s time for watching TV I stop the streamed radio/music. Then I turn on the TV using the TV remote and get NO SOUND :-( neither from TV nor from SONOS AMP. The SONOS AMP does’nt seem to react to the eARC signal but the TV knows that AMP is there since it has switched off its internal speakers. To make it work again I need to unplug the HDMI cable (then TV switches sound to internal speakers to indicate there is no HDMI connected) and then I must reconnect the HDMI cable which causes the SONOS AMP to play sound from the TV (and the TV mutes its internal speakers). And the all is as it should be including TV sound in all SONOS speakers. But

Is anyone using the Arc with a Benq W1070 projector? It has 2 HDMI connections (with no ARC support that I know of) and an old 3.5 mm connector. Are the benefits of the Arc lost with this projector? If not, what is the best way to connect? Thanks.

I have a first Gen setup with Playbar, Sub Gen 1, and 2x Play 1's Gen 1. Also a Bridge. If i purchased a Boost and the new Sonos Arc. Can i just swap out the Playbar and use the new Arc with my Sub and Play 1's     

So I plan on getting an Arc along with my ARC compatible TV.  One of my sources is an xbox one s.  I’ve been trying to research a bit to see how this will all work, but getting a lot of vague answers, even from xbox support site.  Yes, xbox one s (and x) support dolby atmos, but there doesn’t seem to be much detail beyond that.  Here are the questions I have. When watching a blue-ray in TrueHD- Atmos, will the xbox send TrueHD or DD+ to the TV? I saw a reddit user claim that it was DD+, but this was a few years back. Could have been wrong or changed since then. When playing a game with  Atmos, will the xbox send TrueHD or DD+ to the TV? I have seen nothing about the specific code, only the Atmos format.  It appears that some game titles will only do Atmos on the Xbox One X, not S.  I would guess that games are all in DD+, but don’t know why some games will only work on X.  Could it be because X can do True HD while S cannot? When streaming video content, will the xbox send TrueHD or DD

I currently run my Play:3s as surrounds for my Playbar & Sub. Is there any advantage in running Play:3s for rear surrounds vs Play:1 in this configuration?  The sub takes over low frequency duty from the Playbar.  Is the low end pulled out of the rears, as well?  If so, there might be no advantage in running 3s and they might serve better in a stand-alone mission elsewhere in the house. Meaning, they might be overkill for surround duty in this config. Thoughts? -JR

Got a gen 3 sub for use with the arc. Sub would not output sound after connecting via WiFi. Arc used an Ethernet cable. To try and fix the issue,  I tried turning the arc off and back on in order to set it up via WiFi. The arc turned back on but keeps blinking white light. The app can not detect the arc. i now have a non working arc and a sub that I could not get sound out from . Any ideas ?

Hello everyone. Since getting the ARC, I keep having issues with the ARC disconnecting from any audio sources. I have a LG B9 TV with the latest firmware installed. There were supposedly fixes for eARC on this release. Randomly no matter what the source, the ARC HDMI port will show its disconnected. This causes the audio to kick over to the TV, then about 5 seconds it shows the HDMI port has been plugged back in and switches back to the ARC.  Dolby Atmos does work from Netflix, Amazon Xbox1X etc, and it seems like when it is on Atmos it dosent do it at all. Its appears to be only with standard non atmos audio.    I have tried the following:   Swapped HDMI cables from the ARC to the TV. There is currently a HDMI 2.1 cable plugged in, replacing the stock cable that came with it. To be clear it did it on both the stock cable and the new 2.1. Changed audio settings on the HDMI port from the TV. There are only two options per HDMI port. Bitstream and PCM. I have changed the settings f

I recently puchased the Sonos arc, along with gen3 sub and a pair of onesl as surronds. My initial idea was a use a signal box to split the video/audio signal from my apple tv 4k to a benq 4k projector and sonos arc. However, I unfortunately recieved a defective unit from benq, and thus I wanted to buy a tv instead. I know that OLED Tvs are probably best in terms of contast ratio, but I will be moving several times within the next few years, and I really don’t want to be moving those fragile thin screens around. As a result I looked at high end qled and led tvs such as sony x950h and samsung q90t. However, upon reading several threads from this community, I saw that people were having troubles getting their apple tv 4k working properly with sonos arc. This thread for example. It seemed to me that one possible explaination is that sonos arc does not support LPCM. I noticed in one of the threads that someone had gotten their lg CX + Apple TV 4k to send dolby atmos properly, but with ev

I’m not able to connect my new Sonos Arc with the S2 app.   Details of my setup: I have 2x One SLs setup as a stereo pair All devices connected by WiFi My router is a BT Hub 6A (BT Smart Hub 6) No WiFi Extenders Using iPhone XS Max for controller My Arc is detected, I press the sync button and it just fails to connect. Things I’ve tried already: Connecting directly to router via Ethernet Factory Reset Reinstall S2 app on iPhone  Is there anything else I should try? Many thanks,   Adam

I’m getting a hard time trying to keep Sonos Arc connected to Sony Tv. Most of the time the Sonos Arc is displayed on the connected devices list as “Audio System”.  After restarting TV, turning off Bravia Sync (removing registered devices) several times or factory testing Sonos Arc I got to see on the Bravia Sync device list “Sonos Arc”. Then the setup completes and I can use the Sonos Arc. If I turn off the tv and try to watch tv later, the Sonos ARC doesn’t work again. I need to disconnect AppleTV 4K, ps4 and cable STB in order to make it work again.   any ideas?   thanks for your help
