Speaker groups - Configuration challenge

[dark_abyss_]

In speaker groups, you can set the speaker output to play on multiple devices.

For example, you say “Alexa, play music” and it plays on all devices. The issue is that it only works on one trigger device.

How do I get this to be reciprocal and work on all devices (i.e. I go to any Amazon device and say play music and it plays on all of them)?

Create multi room music group, name it "everywhere". Alexa, play everywhere.
