I apologize if I missed this, but the only answers I could find searching the forum where older.



With the release of Amazon's Multi-Room Music SDK (MRM) and the integration of Alexa into the Sonos' One speaker, is it still true you can not play synchronized audio between an amazon echo speaker in one room and a Sonos' speaker in another room?



i.e. You can not create a group that contains both Amazon echo speakers and Sonos speakers that will be synchronize together for music playback.



Thank you in advance for answering this question given any current hardware/software updates.
