When I try to connect my play1 to the system, the play1 do not play the sound-pincode. Is there a way to connect the speaker without it?
Have you done a factory reset on the speaker before attempting to add it to your system?
I have not added a Play 1 in a while, but I do not remember a chime to allow it to be added.
Have a look at this page from the Sonos support site:
