In the Play and PlayStreaming handlers, the old engine's writer thread
still holds an Arc<AlsaDirectStream> when the stream_opt is dropped and
a new snd_pcm_open() is attempted. This causes EBUSY on track switches
with sample rate changes. Reorder to: stop engine -> drop stream -> open
new stream, matching the Stop handler's correct lifecycle.

Show a subtle buffer progress bar in the seekbar when streaming
tracks (before they are fully cached). The bar disappears once
the track is fully buffered.
Backend: expose buffer_progress from BufferedMediaSource through
SharedState -> PlaybackEvent -> playerStore.
Frontend: render .seekbar-buffer bar behind the playback fill.

When backend_type is None (auto-detect), default to SystemDefault on
non-Linux platforms so macOS gets CoreAudio device probing and sample
rate switching instead of falling through to the legacy CPAL path.
Add #[cfg(target_os = "linux")] to pipewire_backend and pulse_backend
modules. Add CpalDefaultBackend for non-Linux platforms using CPAL
default host (CoreAudio on macOS). Gate reset_pipewire_clock() calls.
Add Drop impl to PlaybackEngine so the ALSA Direct writer thread is
properly stopped when the engine is dropped (e.g. streaming timeout).
Previously, a failed streaming attempt would orphan the writer thread,
keeping the ALSA device locked and blocking all subsequent playback.
Also force HTTP/1.1 for audio downloads and add detailed error chain
logging to diagnose persistent "error decoding response body" failures
for specific tracks.
Refactor ALSA Direct engine from thread-per-source to a single
long-lived writer thread with a source queue. When one source ends,
the writer thread immediately picks up the next from the queue with
zero gap. Remove the ALSA Direct gapless rejection gate since the
engine now natively supports source queueing.
Display parental_warning badge (E icon) next to track titles in all
views: TrackRow, QueuePanel, NowPlayingBar, ImmersivePlayer with all
13 visualizer panels, MiniPlayer surfaces, and AlbumDetailView.
Propagate parental_warning field through the full data chain from
Rust backend (qbz-models, queue, commands_v2, session_store, API
server) to frontend stores, adapters, and UI components. Badge uses
CSS mask technique with explicit.svg for theme compatibility.
rodio 0.22's with_supported_config() resets buffer_size to Default via
..Default::default(), so our BufferSize settings in StreamConfig were
never reaching CPAL. MixerDeviceSink has zero internal buffering, making
CPAL's buffer the ONLY buffer between the mixer and audio hardware.
Chain .with_buffer_size(Fixed(sample_rate/10)) AFTER with_supported_config()
to actually pass ~100ms buffer to CPAL, matching old vendored cpal behavior.
- OutputStream/OutputStreamHandle -> DeviceSinkBuilder/MixerDeviceSink
- Sink -> Player (as RodioPlayer)
- current_frame_len -> current_span_len in all Source impls
- Source::channels() returns NonZero<u16>, sample_rate() returns NonZero<u32>
- SamplesBuffer no longer generic, constructor takes NonZero args
- SampleRate is now u32 type alias (no tuple struct)
- Decoder::new_mp4 no longer takes Mp4Type hint
- Applied across both crates/ workspace and src-tauri/ legacy code
Remove vendored rodio and cpal from src-tauri/vendor/ since rodio 0.22
now includes upstream f32 decoder support (our vendored modification).
Update all Cargo.toml files to use rodio 0.22 from crates.io and remove
the [patch.crates-io] section.
The save was broken in two ways:
1. Only current_track + upcoming (capped at 20) were saved, dropping
all history tracks. Queue was reconstructed incomplete on restore.
2. Track metadata (hires, bit_depth, sample_rate, source, etc.) was
not being persisted, only the basic 6 fields.
Add v2_get_all_queue_tracks command that returns the full uncapped
track list with correct current_index. Use it in saveSessionBeforeClose
instead of the capped v2_get_queue_state. Map all metadata fields.
Add experimental toggle to force PipeWire clock.force-quantum alongside
clock.force-rate for true bit-perfect playback. Quantum is matched to
sample rate (1024 for <=48kHz, 2048 for <=96kHz, etc). Both values
reset to 0 on stop and pause-suspend to avoid affecting other apps.
Requires DAC Passthrough to be enabled, PipeWire backend only.
- add Spectral Ribbon analyzer/render path and immersive panel
- tune ribbon density/interpolation and bars edge-bin rendering
- apply artist blacklist filtering to discover index home containers
- include supporting i18n/settings/player wiring changes

Reorganize qbz-player to export the complete Player struct with all
playback functionality.
Changes:
- Restructure: mod.rs -> player/mod.rs with submodules
- Add rodio, serde, reqwest, qbz-qobuz dependencies
- Export Player, SharedState, PlaybackState, PlaybackEvent
- Export streaming types (BufferedMediaSource, etc.)
The Player module is now fully available from qbz-player crate.
Full workspace and src-tauri compile successfully.
Extract player/mod.rs, playback_engine.rs, and streaming_source.rs to
qbz-player crate. Also adds settings.rs and visualizer module to
qbz-audio (Tauri-specific code removed, core functionality retained).
Changes:
- Add settings.rs to qbz-audio with AudioSettings, AudioSettingsStore
- Add visualizer/ to qbz-audio with RingBuffer, TappedSource, VisualizerTap
- Add player module files to qbz-player
- Update all imports from crate::audio to qbz_audio
- Add serde_json dependency to qbz-audio
Full workspace compiles with cargo check.
Extracted QueueManager from qbz-nix to qbz-player crate.
Features:
- Queue manipulation (add, remove, reorder, clear)
- Current track tracking
- Shuffle mode with Fisher-Yates algorithm
- Repeat modes (off, all, one)
- Play history for going back
- Full test coverage preserved
Uses types from qbz-models:
- QueueTrack
- QueueState
- RepeatMode
Phase 3b (player module extraction) deferred - requires:
- Trait abstraction for API client
- Trait abstraction for audio backend
- Config system refactoring
Create the foundational workspace structure for the multi-crate
architecture refactor. This phase establishes placeholder crates
that will be populated in subsequent phases.
Crates created:
- qbz-models: Shared types, events, and traits (Tier 0)
- qbz-audio: Audio backend system (Tier 1)
- qbz-player: Playback engine and queue (Tier 1)
- qbz-qobuz: Qobuz API client (Tier 1)
- qbz-core: Orchestrator (Tier 3)
All crates compile successfully with placeholder implementations.
The workspace uses shared dependencies via workspace.dependencies.
