Arc ultra not connecting

I just bought a Sonos Arc Ultra with Sub gen 4 and 2 Era 300's, I connected the arc to my 5g network, then added the sub, and tested if it worked, I could stream music, no issues. Then I wanted to add the 300's but got the message that they can only be added to a 2G4 network, so I wanted to connect them to 2G4 (different SSID) and then got the message that they would be on a different network than the Arc.

After everything finished, it said that the sub and the 300's were not registered (even though the sub shows up in the living room), but whatever I tried, all the time it says an update must be made but when I activate this it ends with an error 1001.

So I decided to connect all to the 2G4 network, when I update the network all goes well, all is found and it says that my network is now added as trusted network, but then when all is finished and I get to the main screen of the app again, it says there is nothing connected to my network, I restarted everything but same thing, I tried this many times for a couple of hours, but they just won't show up in the app anymore, even though they are found when I search for them or use the update network option.

So now I have a 2500 euro system that won't do anything, very disappointed so far.

Any suggestions? Probably should have bought a Samsung after all….

Hi ​@aneet 

sorry we call a projector a beamer

Ah - got you!

Please be aware that via a Bluetooth connection, you will only get stereo audio - which is a bit of a waste of a Home Theatre system that has more than 20 drivers in use! I don’t know what source you are using (assuming there is one and you are not just using apps on the projector), but if there is a way to connect your Arc Ultra to it rather than to the projector, you may get better audio options (DTS or Dolby Digital, for example), but still will not get the option of Atmos - that requires more bandwidth than a Bluetooth or Optical connection can give.

On the networking side, I agree - if it’s working as is now, there is no need to change anything. But, if you continue to open the app and not get connected on occasion, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

Hi ​@aneet 

Arc Ultra has a multilevel Speech Enhancement option (with the highest being AI powered), but it is only available when the HDMI input is in use. You will not see the option when playing Bluetooth audio.

I highly recommend using another way to get audio to the Arc Ultra if you can. There are devices like the HD Fury Arcana (not a recommendation) that will simulate a TV and provide a eARC port for a Arc Ultra to connect to, while also passing the video out to a TV or projector that does not have eARC itself. They are a bit pricey compared to simpler HDMI switches/extractors, but one would let you get full advantage of the Arc Ultra’s features when using with a projector.

I hope this helps.

I have an Arc HDMI on the projector, it is just a bit of a hassle to get the cable to the Ultra, but I'll figure it out, thanks.

I did see some options in the menu though (night sound and something else regarding voice with 5 levels), however I first have to find out why the app doesn't find the Arc anymore, the strange thing is that if I then goto settings and update the network, it says it is already connected to the same network, and then when I go back to the start page of the app, it says no devices connected, then I restart the app and everything appears again, without having updated the devices

This is where these boxes come in handy - you have the box, the source and the soundbar at the front of the room, and one cable going to the back of the room for video to the projector.

I’d start by rebooting your router - please turn it off for at least 30 seconds when no-one else is using the internet.

I hope this helps.

My projector supports eArc, Dolby Digital plus and dts-hd, so i think just an hdmi cable would be sufficient

Depending on the length of the run, you may need an active, or an active optical (which is basically an optical cable with HDMI converters at each end), HDMI cable. Passive HDMI cables tend to lose signal after 15-20 feet, actives are reliable for 100 feet or more.

Make sure that the long HDMI cable supports HDMI-eARC if you are bringing audio back to ARC from the projector.

so I bought some speaker stands and wanted to retune trueplay, but all the time I just get an error message when starting, ‘something went wrong, we could not finetune your arc ultra, try again’

But whatever I do it keeps bringing this message, first time I did the tuning after install it went fine, now it just doesn't, any advice?

That said, I can't even find the option trueplay in the app, only when I stop the app completely and then restart the app, it will show in the top above ‘your system’, but after a few seconds it is gone and does not show up anywhere.

Strange enough in my products list it only shows the arc, sub and left surround speaker, if I look in the properties all 3 say connected, but if I look in my router client list I only see the Arc, if I do update network, on the Arc all goes well, on the SUB or era300's always same error ‘something went wrong try again’, pfff…..

Are your app and system up to date after last week’s updates to both?

yes, all is updated, and all works fine if I send music to it, all speakers have sound
