Each instance selects and triggers its own cue. The audio path resolves beside this component Source. This works in reading, Focus, and Slides.
<div class="sound-example">
<button type="button" class="pmx-button" data-variant="outline" data-pmx-play-affordance data-pmx-play-icon="play">Play a chime</button>
<x-sfx-cue class="chime" src="./reveal.wav" />
</div>
on("button", "click", () => {
$(".chime").dispatchEvent(new Event("sfx:play"))
})
