how do I remove a room

Hi Robert, If you wish to remove a room, simply disconnect the corresponding device(s) from power. Should you instead wish to rename a device, right-click on the room name, select 'Room Settings' and set any name.

Incomplete. In my prior residence I had Sonos hooked up to my two-channel hi-if system. That system does not exist anymore in my new crib. Yet Sonos keeps it alive as ghost room. Why can't I just click to delete?

Hi Philip. That seems very odd. Has this gone on for long? I frequently change my configuration and Sonos keeps up. Have you tried a complete power cycle of your system? Uninstalling and reinstalling controller? It shouldn't be necessary, I know, but then generally it isn't! John, Canford Cliffs Audio

Thanks for the reply.   

Sonos has been rigged in my new place for four days.  The ghost room was a wired two channel hi-fi in California.   Now in Nashville that system is not even out of the box.

Yes, on power cycling the system.  

No on a reset.  I subscribe to many music services with unique passwords.  Worse is, I have 30 favorites many with unique URLs for high bit streaming.   That is a major pain to reinstall.

Reset is desperado mode.   This is so weird to me.  Everything else about Sonos is dead easy.   Just works.  Not this.

Hi.  I was querying only an uninstall and reinstall of Sonos controller(s), not the whole system, which I wouldn't recommend at all.  I'm pretty sure that Favourites, music services etc are stored in the system, not the Controllers (although maybe you ought to get a second opinion on that!).  Do you have multiple controllers and if so does the ghost room crop up on all?

Yes - on all.  I uninstalled and reinstalled all controllers (6).  No change.

I too have a ghost room from a prior configuration that didn't work. I created 2 new rooms, one for my Play 5s, and one for my Play 1s, both work, but I cannot delete the ghost room. It would be very useful to delete it from my rooms list, as it is the first of 3 in the list on the left of the Sonos Controller, and it confuses me sometimes on Sonos Startup, because it is selected by default and does not work. Any solution for this would be very much appreciated, because I, and every member of my family trip on this ghost room on Sonos Startup; and we loose time figuring out why our music doesn't play.

I would call Sonos support.  There is something very wrong in that the room is hanging on your controller.  Short of starting your system from scratch I don't know what you can do.  But phone support may.

how come nobody answered the question ? How do you uninstall a room ?

Unplug the speaker. What do you actually want to do?
