Some multiroom questions (noob)

Hello all,

I am trying some stuff with Volumio, I think its a wonderfull programm and I have been testing with one RPi and this works great.
Now I am testing with 2 RPi but are some problems I face.

When listening to internet radio through volumio.local I cant “merge” both speakers together to play the same.
When using Airplay or Spoticy I have the oposite problem, eventhough I see both Pi’s I cant only play the music on just one Pi.

Can someone help me with this?

Thanks in advance.

Have a look at the snapcast plugin volumio-plugins-collection-t6251.html
