# Play Audio

For audio that comes from an object in the environment, see [Spatial Audio](/hyperskill-studio-authoring/state-machine-reference/actions/spatial-audio.md). A detailed explanation of controls and interface functions is described in the section [State Machine Builder User Interface](https://docs.google.com/document/d/1-o5qSv4zTkzj7YSmRTkV4zezFq7lwU00FyTy0kw1l1U/edit#bookmark=id.6vu41emx3478).

2. Click on the desired state and, from the dropdown in either the entry or exit actions, select the type Play Audio.
3. Press the + button to add the action to the action list.
