Will Alexa work in a 5.1 Setup with playbar and Ones?

I use l long press on play all over the house, works very well!.

Thanks Ken...will look @alexa groups closely....also the ungrouping auto function...but just tapping play button to hear playbar ON kitchen ONE is alot easier than using sonos app on phone....but now its become a personal challenge....
RegardsThe Logitech Harmony Hub is capable of doing what you are looking for trymph .. you can set an 'Activity’ to group/ungroup your speakers and also control your TV channels and volume on each of the speakers etc. Otherwise the easiest and cheapest method is 'the button press'.

@Ken.....As always thanks for your advise. I added both my Kitchen ONE and Playbar to my Alexa preferred setting in the Kitchen Group. I had also previously turned OFF the ungroup auto play for the playbar in its group or room on sonos app prior (still a bit confused between rooms/groups on alexa vs sonos). When I turned on the TV the Playbar AND my Kitchen ONE both were playing and in sync. When I told Alexa to "stop" she paused the ONE but then resumed playing same audio still as the TV Playbar. When I pressed the play button on the top of ONE audio stopped on the ONE and the led light when green; Playbar unaffected. Later in the evening I asked Alexa the weather with voice and the ONE responded as expected; dont think the TV/Playbar was on at the time however. This is good!
Between my X-1 Xfinity and LG remotes I'd rather not get started with another remote like Harmony. I still have yet to try my Play1/Echo combo in the Den room/group/sonos name. I have a feeling echo works where sonos doesnt based on my experience with the ringdoorbell2 (mentioned b4 that ring says echo skills work but on the drawing board to work similarly with sonos). BTW I also installed the LG "smarthinQ" app in my android samsung phone and registered with amazon & LG where TV does show as a device in alexa app; cant recall if the alexa app sees it as an alexa enabled however FYI.

Update... While TV output plays on both the Playbar & Kitchen ONE asking Alexa to stop has no affect; telling Alexa to change to some music source successfully outputs the music to both Playbar & Kitchen with the TV still on. Manually hitting the play button atop the ONE turns it green and stops both Playbar & ONE; TV output to Playbar will resume when i use the TV remote to up the volume while Alexa stays silent with the green light on. Alexa will resume appropriate verbal commands without turning off the TV and playbar stays on TV output while Alexa follows my new audio verbal command. ....Works for me though........just a FYI
