I am trying to add a preowned sonos sub gen 2 to my home theatre which has a playbase and sonos play 3 surrounds.
When flashing green light appears and I press the join butyon, the flashing green light changes to orange and afyer a few seconds it changes to steady amber.
After some minutes I receive an error message that the sub cannot be added.
Also, many minutes later the flashing green light returns.
The sonos system is running on S1 software.
There are other components in the building, namely, 3xmove, 2xplay 5 gen1, 3x bridge.
I need help to add this sub.
