Playing music on speakers from different brands

Hi all,

At home we have multiple speakers from different brands (Sonos, Google Hub, Samsung Music Frame) and a TV to play sound on.
I’d love for all these speakers to play music in sync (from Spotify), like you can do with multiple Sonos devices.

I’ve been trying to create a flow for this, but I’m not getting very far.

Has anyone tried (and succeeded) this before?

Thanks!

Before you write a flow, you have to find out how to manually stream the same stream at the same time to different speakers. If you don’t succeed in that, a flow will also not succeed in that.
