Sub and amp cut out, no sound

I fixed the amp with a reset and Ethernet cable connection - but the sub won’t play any sound and gives an error message when trying to connect it - yet after closing and opening the Sonos app it says it has been configured.

Diagnosis 894402776

“All of a sudden” certainly suggests either some sort of wifi interference between the speaker and the Sub,  or a failure in the electronics of one of the two speakers. I suppose when someone at Sonos looks at your diagnostic, we’ll know which one it is. Failures of the hardware are rare enough that I’d be expecting some sort of wifi interference, potentially outside of your home network. 

I suspected a wifi interference, but no changes in my network has been made - yet I have done a software update on my router and reset on both the amp and the sub - to no avail, unfortunately.

The sub works, see my most recent answer to Ken.

Does the Amp still work, if you remove its Ethernet cable? Also, just for clarification, when you moved the Sub to the other room, was it bonded to the Sonos One when it was playing? Then when you ‘bonded’ it back to the Amp it then stopped playing - is that what happened, or did it just simply stop playing when you changed its actual physical location, rather than after switching its ‘parent’ (bonded) device?

The Amp still works when I unplug the Ethernet cable.

When I moved the sub around in the app between rooms, it bonded to the Sonos One and started playing immediately. When I reverted it back to the amp, it instantly stopped again.

Sound was been played at all times during this.

Well the checks done so far, seem to ‘infer’ that the Sub is working okay, as it was able to bond with your other Sonos Rooms and play audio. I would perhaps just try another factory reset of the Amp - if it then still doesn’t work with the Sub after that, I would take a further system diagnostic and make a note of it’s reference, then speak to Sonos Support Staff via this LINK.

I just did a factory reset of the Amp, everything works now. It really doesn’t make sense when assuming wifi or wireless connection problems. But it works. Somehow.

Possibly just a ‘glitch’ with the previous reset. The main thing is it’s working.

I would just keep an eye on it and if further problems do occur, then grab the diagnostic and go onto speak with Sonos Support.. but glad to hear all is well at the moment.👍
