* fix(audio): resume playback seamlessly on output device switch (#743) When the OS default output device changed (Bluetooth, USB DAC, HDMI), rodio/cpal had to reopen the stream, which silently stopped the active sink and left the engine with no playback — causing the track to restart from the beginning (or not restart at all after the null-payload bug). Root cause (null-payload): audio_set_device emitted () (unit), which Tauri serialises to JSON null. The null-guard added for the "Rust handled replay internally" signal was therefore also triggered by manual device switches, so playTrack was never called and the engine stayed silent. Fix: audio_set_device now emits the current playback position as f64 (null remains the exclusive "Rust handled" sentinel). Rust-side seamless replay (device watcher path): reopen_output_stream captures a ResumeSnapshot before the blocking stream reopen, then calls try_resume_after_device_change, which: - local files (psysonic-local://): reopens the file, builds a new seekable source, seeks to the saved position — zero frontend round-trip, no audible restart. - fully-cached HTTP tracks (stream_completed_cache / spill file): replays from the in-memory or on-disk bytes — no re-download. - partial downloads / radio / paused: returns false → falls back to the existing frontend path (seekFallbackVisualTarget + playTrack). Frontend (useAudioDeviceBridge): null payload → Rust already resumed; skip playTrack. number payload → call playTrack + seekFallbackVisualTarget(position). Visibility: pub(super) → pub(crate) on the play_input / progress_task helpers that device_watcher.rs needs to call directly. * refactor(audio): split device_resume module; add bridge tests Split the 551-line device_watcher.rs (above the ~500-line soft ceiling) by extracting ResumeSnapshot and try_resume_after_device_change into a dedicated device_resume.rs module. device_watcher.rs is now 320 lines, device_resume.rs 258 lines. Add useAudioDeviceBridge.test.ts: 9 characterisation tests covering the null-payload guard ("Rust replayed, skip playTrack"), the seek-fallback path (position > 0.5 s sets seekFallbackVisualTarget), paused-device branch (resetAudioPause), and the device-reset event path. * chore(changelog): add entry for #765 (device switch seamless resume)
A modern desktop client for self-hosted music libraries
Fast. Native. Beautiful. Built for people who actually care about their music collection.
Psysonic is built primarily for Navidrome and also works with Gonic, Airsonic, LMS and other Subsonic-compatible servers, depending on the features supported by your server.
Available languages: English, German, Spanish, French, Norwegian Bokmål, Dutch, Romanian, Russian and Chinese.
More translations are added over time.
No telemetry • Native performance • Navidrome-first • Community driven
Warning
Psysonic is under active development. Bugs and rough edges can happen, and features may change as the project evolves.
What is Psysonic?
Psysonic is a desktop music client for self-hosted music libraries. It is designed for people who want the freedom of their own server without giving up the comfort, polish and speed of a modern music app.
It is built with Rust, Tauri v2 and React, with a strong focus on responsiveness, customization, practical music-library workflows and a user interface that does not require a manual before you can press play.
Psysonic is optimized first and foremost for Navidrome. Other Subsonic-compatible servers can work well too, but advanced features may depend on server-side support.
