Sub Mini Doesn’t Play after configuration

Hey guys,

i just got my sub mini, correctly added it to the system (beam gen2 + pair of ones) but the sub doesn’t play anything at all. Even with the sub level set up to +15, there’s no sound at all coming out from the sub. 
 

tried probably everything, hard reset, connecting via Ethernet, removing & adding again, checking all setup options inside the app, eventually talked to the support but they also couldn’t help.
 

Have to admit I’m pretty disappointed, and looking at other treads on sub mini issues I’m starting to wonder if this is still the memorable Sonos quality (that you pay for) or some mediocre audio brand?

    Resolved. My amp is hard-wired ethernet and for some reason when that happened, the “Disable WiFi” option was selected in the amp. The Mini Sub is not hard-wired, and Support says the Mini-Sub needs to communicate with the Amp via WiFi (never mind that they’re on the same network anyway). I enabled Wi-Fi on the Amp and everything is working again. Support did say I can run a “No-WiFi” solution but the Amp and Sub would both need to be hard-wired into the network. I don’t have an ethernet jack near my sub, so for the time being the Amp will have WiFi enabled and all is working.

    @Jorge B,
    I will assume you have checked the wiring/polarity with the Amps connected speakers. Are you playing the Spotify audio from the music service built-in to the Sonos App to the Amp ‘room’?

    If so, have you tried increasing the volume-level of the Sub in the Amp room settings and perhaps then carefully touching the two speaker surrounds in the Sub to feel if the two speakers are actually moving?

    If they are moving, but you are still not getting much bass output, then perhaps either try switching their phase 180° to see if that gives a better bass response with your chosen connected speakers, or possibly better still, try the Sub in a different position in the room - I tend to prefer a corner of the room, out in front of the listening position, like the ‘rough’ example shown in the attached drawing.

    What “line out” are you running from your projector? What kind of projector is it? What source are you testing with?

    Hey Jorge- 

    Dumb question… I’m running a line out from my projector to a Sonos amp and the Sonos Sub Mini is not producing any audio. When selecting my audio source I need to choose “Line-in” from my sources, and the Sonos Sub Mini produces no sound. I’ve also tried streaming audio from Spotify to the new Amp and the Sonos doesn’t produce any audio that way either. The sub is “bonded” and shows as part of the group, but it just doesn’t produce any idea. I can toggle it on and off and it makes no difference. Any suggestions?

    What fixed my issue was switching to another ssid… 

    are you broadcasting different bands in your home? 2.4 5 ghz etc? 
     

    my sub mini was doing the exact same thing as what youre saying- saying it was paired with a beam 2 and Ls and Rs but it wasn’t putting out any sound whatsoever- all on the same ssid-

    switching JUST the sub for whatever reason to a different ssid fixed my issue. 

    @Captivebolt Sounds like we dealt with the same thing. I currently have my Sonos gear on the 2.4ghz network. Should I change everything over to the 5G? Or just the sub? What did you do?

    What “line out” are you running from your projector? What kind of projector is it? What source are you testing with?

    It’s an Optoma UHZ50 DLP. The “line out” is the audio out 3.5mm from the projector. It’s a 3.5mm RCA from the projector to the Sonos Amp. The Definitive ceiling speakers plugged into the amp work beautifully, the sonos mini sub doesn’t make a sound. Doesn’t make a difference if I select “line in” as the source on Sonos or Spotify, the Sonos Mini Sub doesn’t do anything.

    Yes, the amp powers the two speakers fine. The sub appears to be working fine from the app, but in practice absolutely no sound comes out of it. I can raise the volume, change the phase, toggle it “on/off” in the settings and there is literally no difference. It isn’t making any sound whatsoever.

    @Jorge B,

    In that case, whilst you are encountering the issues mentioned, it maybe best best to submit a system diagnostic and note or post it’s reference back here and then contact/chat with the Sonos Support Staff via this LINK and see if they can see any issues with the device.
