 ## Acceptance Criteria
 <!-- AC:BEGIN -->
-- [ ] #1 Device selector dropdown in settings view lists available output devices
-- [ ] #2 Switching device preserves current playback position
-- [ ] #3 Selected device persisted in settings and restored on startup
-- [ ] #4 Falls back to default device if saved device unavailable
-- [ ] #5 New audio_list_devices and audio_set_device Tauri commands
-- [ ] #6 Rust unit tests for device enumeration and switching
-- [ ] #7 Playwright E2E test for device selector in settings
