Audio reaches the page through media nodes — a video or a Lottie with sound — and is balanced in the Mixer dock rather than per node. The node's own Mute and Volume are the source level; the mixer is the desk.

> **Browsers block autoplay with sound:** The output window will not play audible media until it has had a user gesture. Plan a click on the output before a show, or run the output muted and take audio elsewhere.
