Specification
https://github.com/WebAudio/web-audio-api/pull/2580
Summary
Introduces an event listener on AudioContext to notify developers of audio device or rendering system failures.
Blink component
Motivation
Currently, developers lack visibility into the success or failure of their AudioContext, whether during its creation or while actively rendering audio. In the event of failure, web applications misleadingly continue to function as if audio playback is proceeding normally.
The AudioContext.onerror event listener allows web applications to proactively respond to and manage device or rendering failures.

WebView application risks

None
Debuggability

No, AudioContext failure scenarios cannot be tested in WPTs. Chromium-internal tests will fully exercise this scenario.
