I have seen much discussion of the Plex ‘skill’ on Alexa concerning Plex playback to speaker groups. The inability to play to speaker groups is frustrating.
NOW, quite accidentally, I think I have found a way that this can be accomplished, quite easily without any tweaking. On a whim one day, I wondered if it was possible to play a stream from Pandora to my everywhere group, something I do frequently, but then on a single echo, request a Plex stream. Well, that worked and I could simultaneously hear both streams being played. The Interesting part is that as soon as the first Plex track ended, I could no longer hear the Pandora playback. Going to another speaker location, I realized all of the speakers were now playing the Plex stream. I have been able to reproduce this several times now, so it isn’t a fluke. Now that the cat is out of the bag, I expect this ‘feature’ might soon be disabled.
