Components and Architectural

I’m having a problem trying to figure out what is wrong with a Sonos connect.The connect is the later s2 device and I have just purchased it 2nd hand.It seem to pair ok and when it updated and went through the register process it seem to fail registration and started flashing  the green light. The light flashes very quickly 3 times then 4 times in a pattern, nothing like the blinking pattern when setting up.Contacted Sonos but they were no help.i did try leaving it unplugged for hours and when I plugged it back in it did show a white light so went into my system and found the device and tried registering again, but the same happened and now all I get is the flashing green sequence. 

I have a Connect:AMP and the volume keeps lowering down automatically in the app. How can I fix this? I tried resetting the Connect and the app, but nothing is working!  Please help!    the diagnostic number is 1481917740.

I have three Sonos Play 3 speakers and a Sonos Bridge. The system is 3 or 4 years old. The bridge stopped working; the speakers seem to have power but the bridge appears to be dead. No lights; just doesn't seem to turn on. Is there a way to confirm whether the bridge is working and if I need a new bridge what should I purchase. I looked at available products and it seems that the bridge is no longer available, but it can be purchased on Amazon.

My entire system is fluctuating volume up and down on its own. It doesn't matter if its just one room or all rooms. It doesn't matter if I play from any one of my phones or computer. I currently have 1 play bar, 6 one(s), 1 Play:5, 1 Sub. Internet connection is great. I have updated the app on all my devices. Has anyone else experienced this? Have you found a fix?

After playing music the audio volume will decrease on its own. After i increase it again, it then decreases by itself. I have a sonos connect connected to an amp that is connected to 2 speakers. The amp is wired stereo to mono as im using one channel for one zone and another channel as another zone. Not sure why this is happening.

Good Morning, I just purchased a BOOST for my home. Easy question. What is the proper way to add the BOOST to an already home Sonos Setup ? Play 5, 3 Play 1's - 2 as a stero pair, Play One, Playbase. I will be plugging the BOOST directly into my router.

Our sonos playbar all of a sudden stopped playing the TV sound. Still can played over but not TV sound nor DVD nor Apple TV. Please help.

Why can't I log in to my Sirius account on the sonos controller
