Maybe see the answer in this earlier thread…

Hi

i have read this post but it doesn’t say if I can connect with the playbar with my phone to listen the music from YouTube or music I have saved on my phone. 
Trying to connect via Bluetooth or airplay but don’t work. 
Is that because the playbar is broken or there is some setting need to be done. 
I can connect via Wi-Fi and operate on sonos app. 

It’s not broken, the Playbar is not Airplay or Bluetooth capable.  Matter of fact, it predates Airplay 2 by a few years. 

Hi. 
Thanks for let me know. 
I will still be looking for 2 speakers and subwoofer. Do you think if any of the other items will be ok to connect via Bluetooth or airplay I can connect all my Sonos items together and play YouTube or my music from my phone. 
If so cold you please recommend me good speaker that will be compatible for Bluetooth or airplay. 
Thanks 

All new Sonos speakers are Airplay capable. As long as you do not ad the new speaker as part of surround set up to a soundbar, you can Airplay to the speaker. If you group the speaker with the Playbar you get the Airplayed sound from  that too.

Not sure which music service you are playing fro  your phone, but most services (Youtube Music, Deezer, Spotify) can be added to the Sonos app. In my experience this gives you a better connection than when you are using Airplay.

Ok thanks. 
What app you use for your sonos that allow you to listen YouTube from you phone. 
when I did add YouTube on this up I couldn’t browse any music  

if you could let me know the app you using I would much appreciated  

Many Thanks  

That’s the S2 app. I use it too for my system. I’m not a Youtube Music user myself, but I can ad it to my phone via settings-ad music services. I seem to remember reading here that you can use a free version of YTM for this.

Please be aware this is Youtube Music, not Youtube.
