Since Godot 4.3, web exports use the Web Audio API for sound by default; you can switch back to Godot’s own audio system in export settings. iOS Safari adds extra constraints (audio needs a user gesture to start, WebGL/memory limits are tighter), so test on real iOS devices, not just desktop browsers.

From Godot 4.3 onward, web exports play sound through the browser’s Web Audio API by default. If you hit compatibility issues with this backend, the export settings let you switch back to Godot’s own audio playback system for the web platform, as described in the Godot web export docs, which also list a set of limitations you should be aware of when porting a Godot game to the web.
For distribution across web portals, Playgama Bridge provides a Godot 4 plugin to connect platform APIs.
iOS Safari is where most of these limitations surface first: audio contexts generally need to be resumed by a user gesture (tap or click) before any sound plays, so a game that starts audio automatically on load will be silent on iOS until the player interacts. Test both audio backends on an actual iOS device, since desktop Safari and Chrome do not reproduce all of Safari mobile’s quirks. Also budget extra QA time for WebGL and memory behavior on older iOS devices, which tend to be stricter than desktop.
What should I check before shipping a Godot 4 web build?
- Confirm which audio backend is active in export settings and test both if unsure.
- Trigger the first sound only after a user tap, not on load.
- Test on real iOS hardware, not just browser dev tools.
- Check the Godot web export limitations list for anything else affecting your game’s features.

Why is there no sound on iOS Safari in my Godot web export?
iOS requires a user gesture like a tap before audio can start; if your game plays sound automatically on load, it will be silent until the player interacts.
Can I use Godot’s old audio system instead of Web Audio API on web?
Yes, Godot 4 web export settings let you switch back to Godot’s own audio playback system if the Web Audio API backend causes issues.
