Not sure exactly what you want, but to make this change you'll modify this file: https://github.com/NickBorgers/node-red/blob/master/configs/music_config.yaml You [could manipulate the `default_volume`](https://github.com/NickBorgers/node-red/blob/master/configs/music_config.yaml#L33), or perhaps [add another criteria for `leave_muted_if`](https://github.com/NickBorgers/node-red/blob/master/configs/music_config.yaml#L34-L38).
