I currently have a 5.1 surround set up using a gen 1 sub, beam, and 2 One SLs. My sub randomly stopped working the other day and upon trying to reconnect/reset/repair everything, it will not play any audio. Prior to it stop working it was making a random periodic popping sound. This is when I tried resetting it and reconnecting. At first it wouldn't connect, now it'll show it connects fine but will not play any audio when linked to my 5.1 or my other Sonos one in the kitchen. Is the sub just toast now? I've also tried using WiFi and Ethernet, no luck with either. 

Here's the diagnostic code: 1200403642
