Hi @Dubs99
Welcome to the Sonos Community!
You’ve received some conflicting information, so I’ll clarify things for you a little:
Sonos Amps used in conjunction with Sonance Architectural do support TruePlay. However, for TruePlay to be available, there cannot be a mix of different speaker types connected to the same Amp, nor can there be any switches or volume controls fitted between the Amp and the speakers.
Please also ensure there are no loose connections either at the Amp or at the speakers.
If you continue to see this issue, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.
I hope this helps.
