Multi-room group playback with Google Home

Group any combination of Google Home devices, Chromecast Audio devices, and speakers with Chromecast built-in together for synchronous music throughout the home. Your favorite music and audio from Chromecast-enabled apps are instantly available to stream.

"Audio devices" includes Google Home devices (Google Home and Google Home Mini), Chromecast Audio devices, and speakers with Chromecast built-in.

Note: Creating groups for video devices like Chromecast isn't currently supported.

Playing audio groups is like playing audio on individual remote devices except you’ll say “Ok Google, … on <group name>" instead of “Ok Google,… on <device name>".

Note: Make sure to voice-enable the group to control it with your voice.

To do this...	Say "Ok Google" or “Hey Google," then...
Play music using group name	“Play rock on <group name>”
Control music using basic commands	“Pause, resume, stop, play next song”
Control volume Note: During group playback, volume commands only change the local Google Home device unless you say "Ok Google, ... on <Group name>."	"Set volume to 5," "Set volume to 40%"
