It’s not yet possible to run Trueplay on inverted Eras. I think - but it’ll be good if Sonos will confirm this - that’s what they’re referring to. But, the guide also says “not yet…” so hopefully it’ll be supported soon. 

Thanks a lot. I’ll wait  we unfortunately have no choice… 

We already had problems with TruePlay before they made this new Sonos 2 app -2.0

Is there a place in this community site to let know to Sonos (if they come around) to mention our wishlist (improvals or new setups) for this Sonos app ?

for instance :

•  when you try to perform Truplay, the iPhone app Goes to sleep if you don't press the screen which make no sense,

• recently, when you try to perform Truplay, the truplay sound sequences are so loud that you can wake up all the neighborhood !

I would have a lot more…

Sonos ask us to please ignore this erroneously generated message:

Thank for the link of the very same problem I meet… but that I didn’t find before posting. 
 

Hi @Rudy A-Traxx 

I am happy to confirm that TruePlay Tuning now supports the use of inverted Era 300s in a Home Theatre setup.

I hope this helps.

Thanks for this update. 
by the way, is it something brand brand new ? 
I recently bought the Arc ULTRA and a couple of days did a Trueplay. 
should I do it again ? 
 

thanks.

Hi @Rudy A-Traxx 

I’m not sure exactly when this was resolved, but I think it was fairly recently, yes.

No need - if TruePlay completed at all with Era 300s in an inverted position, then all went well!

I hope this helps.
