Add semaphore to limit concurrent prefetch operations to 1 at a time.
This helps prevent potential race conditions in native audio libraries
(CPAL/PipeWire/ALSA) that can cause malloc corruption.
Also:
- Reduce QOBUZ_PREFETCH_COUNT from 3 to 2
- Reduce PREFETCH_LOOKAHEAD from 15 to 10
- Add 50ms delay before cache insertion
Addresses #38 - random crashes during prefetch
Implement 9/10 check strategy:
- 9 out of 10 connectivity checks go to 1.1.1.1 (Cloudflare DNS)
- 1 out of 10 checks go to Qobuz to verify service availability
This prevents false offline detections when the app is making many
concurrent API calls (e.g., loading genre hierarchies), which could
trigger Qobuz rate limiting and cause timeout-based false positives.
Also reduced timeout from 15s to 10s and retry wait from 2s to 1s
since 1.1.1.1 responds much faster than Qobuz.
Only show expand carets in the advanced view for genres that actually
have children loaded, or where children haven't been loaded yet.
Applies to all levels (parent, child, grandchild).
- Add silent parameter to loadChildren to skip notification
- loadAllDescendants now loads children and grandchildren in parallel
- Only one notification after all loads complete (no triple reload)
- Lazy load children only when tree node is expanded (faster startup)
- Fix popup positioning to grow left when toggling advanced view
- Eagerly load all descendants when selecting a parent for filtering
- This ensures basic mode also filters by Genre > Children > Grandchildren
- Show loading spinner while fetching children
- Parent genres shown as headers with checkbox
- Children displayed in grid below each parent
- Clicking parent toggles all its children
- Partial selection shows indeterminate state on parent
- Popup expands 150px taller when in advanced view
- Default view shows only parent genres (less cluttered like Qobuz)
- When selecting a parent, filtering includes all its sub-genres
- Added "Show all sub-genres" toggle for granular control
- Store now tracks parent/child relationships for proper filtering
- getFilterGenreNames() returns selected + children for filtering
Fetch parent genres first, then fetch sub-genres for each parent in
parallel. Combine into a flat list sorted alphabetically. This fixes
the issue where albums with sub-genres (like Alternative & Indie,
Opera, Concertos) were filtered out even when all genres were selected.
Add FavoritePlaylistCard component with hover overlay containing:
- Heart button (remove from favorites)
- Play button (start playlist playback)
- More menu (play next, add to queue, share, remove)
Card click navigates to playlist page. Updates FavoritesView to use
the new component with all action handlers wired through +page.svelte.
- Add 'control' variant for Favorites style matching other dropdowns
- Add 'align' prop: 'left' (Home) or 'right' (Favorites)
- FavoritesView uses control variant with right alignment
- Control variant shows "Genre: X" with chevron icon
- Add GenreFilterButton to Favorites > Albums toolbar
- Filter albums by genre name (multi-select supported)
- Use genreFilterVersion for reactivity tracking
Note: Artists tab doesn't have genre filter since artist
objects don't contain genre info directly.
- Allow multiple genre selection (checkbox behavior)
- Add getSelectedGenreNames() for multiple name retrieval
- Merge results from multiple API calls for featured albums
- Clear button now closes the popup
- Button shows "N genres" when multiple selected
- Add getSelectedGenreName() to genre filter store
- Add filterAlbumsByGenre() helper in HomeView
- Apply genre filter to Recently Played and Favorite Albums
- Fetch 3x more items when filtering to ensure enough results
- Reduce card height from aspect-ratio to fixed 36px
- Use neutral bg-tertiary background instead of colored gradients
- Horizontal layout with name and check circle
- Selected state uses accent-primary
- Better spacing to prevent overlap
Use onMount instead of $effect to load genres once.
Add initialized flag to prevent onFilterChange from firing
during initial subscription setup, which was causing
loadHome -> re-render -> loadGenres -> notify -> loadHome loop.
Remove genre_id from base schema and let migration add it.
This ensures existing databases don't fail when trying to create
index on non-existent column during initial schema execution.
- Add GenreFilterButton to home header
- Pass genre_id to fetchFeaturedAlbums API calls
- Reload home content when genre filter changes
- Featured sections now filter by selected genre
- Add reco_backfill_genres command to populate genre_id for existing events
- Add reco_needs_genre_backfill command to check if backfill is needed
- Fetches album details from Qobuz API and updates events in batches
- Includes rate limiting to avoid API throttling
- Add genre_id column to reco_events table
- Add migration to add column to existing databases
- Update RecoEventInput and RecoEventRecord structs
- Update insert_event and get_events_since to handle genre_id
- Add get_album_ids_without_genre() for backfill
- Add update_genre_for_album() for backfill
- Add optional genre_id parameter to client method
- Add optional genre_id parameter to Tauri command
- Qobuz API filters featured albums by genre when provided
- Add playPlaylistById to set queue and play first track
- Add queuePlaylistNextById to add playlist tracks next
- Add queuePlaylistLaterById to add playlist tracks later
- Add copyPlaylistToLibraryById using subscribe_playlist
- Add sharePlaylistQobuzLinkById to copy link to clipboard
- Connect all handlers to SearchView component
- Repositioned toggle to appear right after Streaming Quality dropdown
- Updated description to clarify it overrides quality setting when device
doesn't support the selected sample rate
Frontend changes for quality limiting feature:
- Add limitQualityToDevice state and handler
- Add AudioSettings interface fields for limit_quality_to_device and device_max_sample_rate
- Update handleBackendDeviceChange to send max_sample_rate when device changes
- Update handleOutputDeviceChange to find max_sample_rate from backend devices
- Add Settings UI toggle for "Limit Quality to Device"
This completes the quality limiting feature that prevents requesting tracks
that exceed the device's sample rate capabilities, ensuring bit-perfect playback.
- Add limit_quality_to_device setting (enabled by default)
- Add device_max_sample_rate field to store selected device's max rate
- Implement limit_quality_for_device() to restrict quality based on device
- Apply quality limiting in play_track and prefetch_track commands
- Add set_audio_device_max_sample_rate Tauri command
This ensures bit-perfect playback by not requesting tracks that
exceed the device's sample rate capabilities. When enabled:
- Devices <= 48kHz: limited to Lossless (44.1kHz)
- Devices <= 96kHz: limited to HiRes (up to 96kHz)
- Devices > 96kHz: allow UltraHiRes (up to 192kHz)
Add new audio setting to limit streaming quality based on device
capabilities. When enabled (default: true), QBZ will avoid requesting
tracks that exceed the device's max supported sample rate.
This ensures bit-perfect playback by preventing the need to resample
high-res tracks on devices that don't support them.
- Add limit_quality_to_device field to AudioSettings
- Add database migration for new column
- Add Tauri command for frontend integration
cc
- Add AlsaDirectError enum for structured error classification
- Add BitPerfectMode enum to track runtime bit-perfect status
- Implement automatic fallback: hw fails with format error → try plughw
- Abort on non-recoverable errors (busy, permissions, invalid params)
- Respect ALSA plugin selection from UI settings
- Log runtime mode for debugging
This allows SMSL-class DACs that fail on hw: to work via plughw:
while maintaining bit-perfect guarantees (format conversion only,
no resampling).
cc
- Add S24_3LE (S243LE) to format priority list as first choice
- Implement S24_3LE write handler with 3-byte packed conversion
- Add S24LE write handler (was missing explicit implementation)
- Reorder format priority: S24_3LE > S32LE > S24LE > S16LE > FloatLE
This fixes bit-perfect playback on USB DACs that only support
the S24_3LE format (SMSL, Topping, Fosi with TAS1020B chip).
