lossless via Apple Music

I've had Sonos since the early 2000s and don't recall any that wouldn't play lossless music.

Sonos plays what you send it, send lossless it plays it. 

I don't use Apple but these may help

 Do you have issues with the Play 1 speakers playing from the integrated Apple Music app?  The Play 1 is limited to 16/44.1 while the ERA 100 can play 48/24.  I would imagine the Apple Music app in the Sonos app will play to both the Play 1 & the ERA 100.  If you’re playing from a local library those bit rate / sample rate limitations may come into play.  Unless Sonos has done something with down conversion.  I don’t have any legacy devices to test that.

Note that you can’t (using Sonos software) pair a One and a PLAY:1, but they can be grouped. You may find it beneficial, if you’re after a stereo setup, to set the two PLAY:1s in one Sonos ‘room’, and the two Ones in another. Then you’d be able to stereo pair them, rather than grouping them. I know, it’s a pain, but Sonos terminology is particular, and explained in the Sonos terminology thread.

They are grouped, sorry that was me using the wrong terminology. 
 

if I paired them I seem to recall that there was an issue with the play:1 speakers. Without the One to control I’m sure I couldn’t group them or something?!? 

Thanks, so I can’t play lossless via the main speakers, but my era 100 should? 
 

in that case do I need to do anything to enable it? 

​@MrWheelbarrow, When you group the Play:1s to the ONEs and/or Era 100s, the playback will revert to lossy.

AirPlay or Bluetooth playback would potentially be a reason to group them that way, the PLAY:1s don’t have either ability, while the Ones do. 

Thanks, I knew there was a reason. 

It’s the only thing I could think of, from my usage, that made sense…although I’ve done it the way I suggested, and when using AirPlay or Bluetooth, I just group the two rooms…the one that”s the target, and the one I’m listening to. That way, I get stereo, all the time, no matter what. And yes, stereo is important to me, why do you ask? ;)

I seem to remember that SUb Gen 1 and 2 will play lossless in a Home Theatre surround set up as opposed to running them with a Stereo Pair.

So if I am playing through the era 100 why isn’t it saying it’s playing lossless on the Sonos app display?
