Playback State Consistent Across Lock Screen
Restructured the playback layer so the in-app player, lock screen controls, and native audio path share a single, consistent playback state.
A smooth in-app playback experience is insufficient if the lock screen and Control Center display state that differs from what is actually playing. This work focused on ensuring the in-app player, lock screen remote controls, and native audio path all reflect the same playback state at all times.
The scope covered the full playback infrastructure: audio session management, track loading, video transitions and looping, and the points where effects and reverb are applied. Fragmented audio processing paths were consolidated so that a state change at any layer propagates consistently across all others. Data sync and caching were also aligned to deliver content against the same source of truth.
Continuity on screen re-entry and the flow through splash and onboarding on first launch were addressed within the same scope. The outcome is a playback architecture where a single user action produces a consistent state across every surface of the app.
