Sonos has announced that Apple Music will arrive for the speaker system on December 15, 2015, which is just over two weeks from now. However, Apple Music will still be in beta on Sonos at that time, so there will still be fine-tuning taking place once the service rolls out.
On Sonos, users will be able to listen to music from all of Apple Music's sections, including For You, New, Radio, and My Music. As it will still be in beta, you'll need to join the Sonos beta program. You'll do this by going to your Sonos app, then Settings > Advanced Settings > Beta Program > Join Beta Program. You'll then be able to add Apple Music as a service when it appears on December 15.
