"Sonos: Play5" endpoint issues - "transport lost control of audio device" error

Hi @Ian_Celing ----- Thank you for the report and sharing your observations with us. Both are very appreciated. Sorry to hear of the troubles. I have went ahead and split your post out to it’s own topic so we can address this behavior with you directly.

Moving forward, to help aide in our understanding of this behavior you are experiencing, may I very kindly ask you to please provide me with the following:

  • Please verify how close in proximity the Boost is to the mentioned router. I had another user not long ago report a similar issue and it was discovered that the Sonos manual recommends keeping the boost at least 1 foot from the router being implemented.

  • I understand based on your post that the Play:5 is communicating with the sub-network being created by the Boost. During your troubleshooting have you tried testing with the Boost disabled (temporarily of course) to see how the system behaves?
