Sonos:Sub not working

I have the same issue, currently have a playbar in living room, play 1 in kitchen and another in bedroom (all wireless). I can only manage to get the sub to connect via wired to the router, and even then when i add it to either of the play 1’s it works, but if i add it to the playbar, it says added, but theres no sound from the sub… I havent been able to get the sub connected wirelessly at all after trying everything, as soon as i take the cable out (when paired with the play1) it just disconnects.

Contacted sonos who had me on the phone doing the exact same tests ive already done for hours, to be told its probably the wireless card in the sub and that because its 3 years old id have to pay £450 for a replacement!!!! WTF

Its an absolute joke!

If the wireless card is dead, would that be why it doesnt have any sound when connected to the playbar? because i dont see why it would work with the play 1 but not the playbar.

Im so fuming, a 3 year old £799 product that is designed for wireless music shouldnt just fail...

My sub no longer works. I have removed from it and factory reset it 
but unfortunately no sound.  I also rebooted my network. 
Here is the diagnostic report number:39580312

Hi @wcepedaasub, welcome to the Sonos Community!

I’m not seeing any obvious issues in the diagnostic, aside from a little wireless noise in the 5GHz range, nothing that should be preventing the Sub from working however.

Would it be possible to test the Sub connected to the Playbase rather than the Playbar? Another option would be to test wiring the Sub directly to the Playbar via Ethernet cable (you would need to leave the Playbar connected to the router however), which would rule out interference as an issue.

Let us know how you get on :)

3 month old sub having same issues as everyone else. Not interested in being told its defective and paying to fix it like others have so contemplating getting money back and going for wired system. nothing worse than unreliable IT garbage

My sub no longer works. I have removed from it and factory reset it 
but unfortunately no sound.  

I tested wiring the Sub directly to the Playbar via Ethernet cable and reset & configure it as you recommended but no sound from the sub.  The diagnostic confirmation # is: 1338909531.

The Sub works using an ad-hoc 5Ghz WiFi connection to the room it’s bonded with - so ensure the radio is switched ‘on’ in the Playbar room settings in the App, try toggling it ‘off’ and ‘on’ again.

Also try attaching the Sub to a different Sonos room (if you have one available) to see if it then works, if it does, then that may point to an issue (perhaps) that your 5Ghz wireless adapter isn’t working on the Playbar, rather than it being a Sub issue… it’s worth moving the Sub aswell to a different position and much nearer the playbar when testing the connection between the two units.

I Also try attaching the Sub to a different Sonos room (Play Base - Bedroom) and the Sub doesn’t  work, As you said. I  already have connected to the play bar two Play1 (Left & Right) and are working fine. I merge the play bar and Play Base and works perfectly. Just the SUB is not working. I’m struggling with this issue for months and nothing that can help to solve this annoying SONOS issue. When I check the SONOS devices at your portal all are ONLINE except the SUB.

Your confirmation number is: 782153502.

Just to make it clear, I’m just a Sonos user, like yourself.

As you have tried the suggestion of ‘bonding’ the Sub to another room and have wired the sub to the LAN and have already factory reset it aswell, then it’s perhaps best you contact/chat to Sonos Support Staff via this LINK and see what they can perhaps discover from your diagnostic report.

After hundred hours invested, they offer replace the SONOS Sub defective for a refurbished one paying ~ $400 (Originally paid ~$700) total more than one thousand. I was expecting a repair option but not. END of the history.
