Not communicating with Wireless M7 speakers and hub

I can get the 2 M7 multi-room speakers to show up in the smartthings app but they are completely not functional… I’ve practically given up after trying a number of different things.

Please help

what are you trying to do with the speakers? The Integration is very limited and in my experience with my M3’s and M5’s it only allows you to increase or decrease volume, pause and play when you already have music playing from the Samsung multiroom app.
I have had success in using EchoSistant to make voice announcements.
