No.  Unless you are using the Sonos Architectural speakers for your mains, the Amp does not support any kind of Trueplay for a Home Theater setup.

Then why do the docs say:

“

Amp and Connect:Amp also support Trueplay when powering any third-party surround speakers in a Sonos home theater setup.

“

Rather than me spending a bunch of time looking, where did you find that said?

The poster is right.  I was misinformed, or that functionality has changed

I’m sure that is new, it used to be only the Sonos special Sonance speakers that were supported.

For such major good news I have no idea why Sonos isn’t promoting that. Both folks looking into Sonos and a lot of existing users that have been told it wasn’t an option would like to know about it.

Reading that it appears that you only get Trueplay on surrounds in a theater setup, not when just the TV’s front channels, a stereo pair or single speaker.

BUT here it the Amp document says: (seems my computer can’t select and copy there)

The Amp’s manual says nothing that I can find.

@jgatie I’d say it has changed. My memory matches yours, it previously was not supported. 

Wonder when that change occurred?

Well, the other night support read that article to me as proof that it’s not supported.  How can we get a clear answer?

Wait for the Sonos forum rep to see this topic and respond.

FWIW, it’s willing to start, and then says lost a speaker (does not explain what lost means, or which speaker) after 10 or 20 seconds of the tones.
