Hi

i have needing using Sonos amp with wireless Sonos beakers and a wired set of ceiling speakers the cables go into the back of the amp.

i use to select the ceiling speakers when I wanted to use them 

now they do not  appear as an option ? 
 

tried turning on and off the Sonos amp but it makes no difference Tried adding speakers but it just looks for wireless speakers Many of my wireless speakers have been lost but the beam with my tv is still available and I can select and play Spotify through it 

any suggestions as to what I should try 

cannot understand if the cable goes from the amp to speaks why it cannot find them
