    Hi there, geezfab. Thanks for posting. Happy to help in any way I can. Could you tell us a little more about how you are using the CONNECT:AMP? For instance, if you are using this CONNECT:AMP to power surrounds, the Subwoofer out will not function. Read more about this here.

    If not, I would recommend giving our support technicians a call. They can do some troubleshooting in real time and replace the unit for you should the need arise. Our contact information can be found here. Additionally, I would test the Subwoofer with another audio source, just to make sure there isn't a problem with the speaker itself.

    Thanks again!

    See this working link below that I believe Keith N. was referring to in his earlier post ...

    https://support.sonos.com/s/article/2237

    Take particular note of the second bullet point shown under the heading of 'General Guidelines' in that support article.

    thx. I do have sound on regular speakers, just nothing on the sub. I have my home in-wall speakers hardwired to the back of Connect amp and they work just fine. and then I have a Velodyne sub connected, and it's not emitting any sound. The sub works when I plug into a different source. any ideas?

    Is it a 'powered' sub and have you switched it on? ... see this link:

    https://en.community.sonos.com/components-228996/line-out-to-subwoofer-6794927

    It looks like the Amp should detect it as soon as it is powered on and should set the crossover frequency automatically to 80hz too.
