To learn more on how to add audio to your Rive file, see Audio Events.
On the web, most browsers restrict audio from playing until the web page is interacted with. This applies to any audio, not just Rive audio.The web page needs to receive some interaction (touch/click) before sound is played. This interaction can be anything on the browser and doesn’t need to be a Rive specific interaction.
Embedded Assets
Embedded assets require no additional work to play audio.
Referenced Assets
Referenced assets require a little bit more work to play audio. Audio will still automatically play, but the audio file(s) must be loaded when a Rive runtime attempts to play audio.
For more information, see Loading Assets.
