I have recently replaced some older Sonos components (Zp100) with newer Amps and added a Playbar, so my system is now SonosNet 2.0. I anticipated this upgrade would solve an ongoing issue and allow me increased bandwidth for allowing Apple Lossless to be played ‘Everywhere’ ie all rooms/party mode, but I’m still unable to do this.
I am starting the playback from the Ethernet connected device, then adding the other rooms, but it still fails. MP3 plays fine. SonosNet supports 32 devices, but is there a lower limit than this for playing lossless formats?

First, try switching to compressed audio and see if that helps. It may not but it is an easy fix.
More difficult is trying to optimize the SonosNet mesh. Having more wired devices is usually a good thing, the more wired the less wireless traffic and the more possible paths for the data to flow. Only glitch might be STP but that is easily sorted using the tips around here.
I’d start with the Network Matrix, use your IP not mine: http://172.16.1.111:1400/support/review
Give it a look and see if you see any issues, you can search here for what the different things mean and post a legible copy of yours for other folks to comment on.
The basic wireless link has a lot of excess bandwidth if interference is low, if there is more then retransmissions and such can clog things up a bit.
You can also wait for a glitch and submit a diagnostic, contact Sonos support directly with the diagnostic number and the problem you are seeing and they can see stuff we users can’t. Some of the options on the contact page are staffed 24x7 too.
