Speaker group Questions?

Hello, I just recently discovered groups, or at least realized I could group all my Google homes (10) and my 1 Sonos speaker. I can send TTS messages across all devices but fall short on playing music.

Seems like this should be simple but my search did not yield amnything. Are there any audio players that I can use in HA that allows me to choose the custom group I made to play music over? Really, for my use it just adds the Sonos as I have all the others grouped natively in Google Home app.

Thank you for your time,
