Era 300s wont connect to Arc for Surround

Assuming the Sonos hardware is okay then the next thing I would try, is a Sonos App reset ‘Settings/App Preferences’. See this support link: https://support.sonos.com/en-us/article/reset-the-sonos-app

On reopening the Sonos App, post reset, accept the T&C’s and connect it back to the ‘existing’ Sonos system.

If that doesn’t solve it, then it’s time to look at the router settings/firmware, but I would need the make/model to do that here and check to see if it’s firmware has been updated recently.

ARC + (2) Era 300s. Set up ARC, added Eras as separate rooms, tested music playing through each three. All three on wifi; Comcast all-in-one modem so theres no picky firewall stopping anything. Added Eras as surrounds and app says it’s all good. Start streaming movies and no surround audio. Check app and it shows the two Era 300s as NOT CONNECTED. I’ve reset and gone thru the setup four times already. I’m assuming there’s a firmware bug causing this or is the Eras as surrounds just not ready for showtime?

All three setup as separated rooms, grouped them under the ARC playing tv audio. Somehow the app forced the Eras to populate as surrounds in the app but they’re still not playing any audio

What audio codec is playing to the room? If it’s PCM 2.0 then you’re not going to get any audio output from the rear channel speakers, you need to provide more detail about what the TV/Peripheral is sending to the Soundbar. As a quick check the ‘Now Playing’ screen in the App will show you the input to the Arc or you can goto ‘Settings/System/About My System’ and find the Arc in the device list and when it’s playing checkout what’s showing next to Audio In:

Ideally, the codec needs to be DD or DTS 5.1 surround sound or similar, not stereo audio.

@Ken_Griffiths i have to get past the Eras showing not connected before moving in to that. Or are you implying that they show as not connected when in stereo?

I don’t quite understand, as you did mention this earlier… ‘Somehow the app forced the Eras to populate as surrounds in the app” ..?

@Ken_Griffiths yes. So last reset had them all as separate rooms, grouped them together and the eras showed up as surrounds in under the Living Room ARC. Played Guardians of the Galaxy and still no audio out of the Eras. Tried full channel music thru Apple Music and still nothing. I’ll try again later this morning and see where I get

Maybe describe (or screenshot) what you’re seeing as your Sonos Arc Room Name in ‘Settings/System’ in the Sonos App. Also check the ‘Audio In’ on the Arc room, as mentioned earlier.

Ensure you’re ‘bonding’ the surround speakers to the Arc through the Arc ‘room’ settings in ‘Settings/System/[Arc Room Name]’ and not simply ‘grouping’ the speakers together in the System/Rooms main tab.

If you’re TV/Source device is not sending out the correct audio, then you may only get stereo by default anyway, so check you’re ‘Sound Out’ settings, particularly on the connected TV itself.
