If iTunes on your Mac supports “Last Played” and play counts, then it shouldn’t be a problem when connected to a Sonos speaker over AirPlay. And it should also work over Bluetooth to a Sonos Move or Roam.

The only way to know for sure is to test it yourself.

Yes, your Sonos will show up as an AirPlay speaker on your Mac.

GuitarSuperstar: The Last Played and play counts work when I play through my Mac music app on my iPhone and use AirPlay to play through my Sonos speakers -- which is a good work around. However the Last Played and play counts don’t work on my iTunes on my Mac when I click on the Sonos speakers via Airplay. Of course the Last Played and counts work when it’s solely my computer speaker. Thanks for your reply. 

That certainly suggests an issue with Apple’s software on the Mac specifically, ignoring AirPlay 2 as a source for counting. None of the “counting” software is at the speaker level. You could, however, prove me wrong, if you have a set of non-Sonos speakers you can use AirPlay 2 to connect to from the Mac, and show that iTunes is counting in that case. 

It may be worth checking with Apple about that, since it certainly seems odd that it works one way on your iOS device, and another on the MacOS device. 

I purchased a HomePod mini. Basically it’s the same issue. The Last Played and Play counts work fine if I’m playing music from my iTunes via my iPhone and AirPlay 2.

When I play music from iTunes via my Mac the Last Played and the Play counts work if it’s the Mac alone. When I add either a Sonos speaker or the new HomePod mini via AirPlay 2 the Last Played and the Play counts do Not work. So Airgetlam, I believe you are correct. Thanks for the feedback.

I spent considerable time with Apple Support. They understood the situation. My “case” has been kicked to the Engineering department. We shall see. Thanks to all the Sonos community.
