I have tried Truplay on my Playbar, with Play:1's as surrounds about a dozen times and it fails each time.
It tells me I need to move around the room more. If I literally run around the room all over with phone below my knees and above my head it tells me there is too much noise. (probably due to the cracks in the floor and the "wind" effect on the microphone.)
So how many times do you need to loop around the room? I have tried going to each spot I can twice and it's still not enough.
I am trying it with a iPhone SE and also with an iPhone 5. Both semi old phones but that's all I have for apple products.
FYI, I have lots of furniture in the room, so there is only so many places I can walk. The room is about 20x16 feet.
