How many speakers with Arc?

@EdFlip Probably not, since @Networthy says he has “an Arc bonded with 2 Sonos Fives". Bonded in Sonos terms means "set up as a surround set", and Sonos only allows a set up where the extra speakers bonded to a soundbar act as rear speakers.

My Arc, subwoofer and 5s are in a physical row with the 5s like the TV facing into the room with seating opposite. The ones are level with the seating in the corners of the room. 

And the Fives are bonded in a surround set up (so set up as rear speakers while being used as front speakers) and the One’s are grouped? And this does not sound strange?

Aha I had naively assumed that as I’d danced round with my phone as part of the setup Sonos ‘knew’ where the speakers were. I’ll try reconfiguring. Really disappointing you can’t bond them all as there’s no delay so I think Sonos is missing a trick. Thanks. 

The trueplay tuning you did is for a single Sonos room.  In your example, you have two Sonos rooms (Arc+ 2 Fives and 2 Ones) even though they happen to be physically in the same room.  As far as the delay goes, the Arc and speakers bonded to it will play TV audio immediately so that it stays in sync with the video on your screen.  And Sonos rooms grouped to the room connected to the TV will be buffered/delayed.  You may not notice the delay, or you can increase the delay on the Arc so that it doesn’t match the video as well, but matches a grouped room better.  Not sure if this is what you did, or if the echo just isn’t noticable or bothersome to you.

Played around with the delay and it sounds fine. Will move speakers though. Thanks. 

Ok thanks for the clarification.  I did do the true play,  But I don’t have the room totally complete. So I disabled it for now.  I will play with it a little bit.
