Soundtouch group play not working
Hello I am hoping someone can help, I have the Soundtouc 300 sound bar, several soundtouch 10 and one soundtouch 30 around the house. I have connected them all to the network and can control them all individually from my phone, but when I select "play all" from the app, only the speker that I used to begin the "play all feature actually produces sound. The app says they are all connected and playing (the soundtouch 30 even displays the title of the song properly so I know i t is connected) but the sound only comes from whichever system i used to begin the "play all". What am I missing?
