This post is from the WWDC26 Audio Q&A.
With SiriKit deprecated in iOS 27, I'm implementing App Intents from scratch for a frequency/ambient sound app. Should I conform to AudioPlaybackIntent from the Media framework or build a custom AppIntent? Specifically, I need intents for: play a named frequency, start sleep timer with duration, stop playback. Is there a recommended Intent entity type for audio content that isn't music (i.e. not MusicKit-backed)?
