Summary

Unplugging the output device (or switching audio outputs) while native streaming is playing freezes spotatui on Windows forever. The fork's rodio 0.21 RodioSink has three faults that combine into the hang:

• rodio's default error callback eprintln!s the failure into the TUI;
• write spins on Sink::len() > 26 forever, because a dead device never drains the queue;
• stop calls sleep_until_end(), which never returns either.

This PR replaces that sink with a custom SpotatuiSink (src/infra/player/sink.rs, rodio 0.22) on Windows, unless the user explicitly names a backend via native_backend(). The new sink:

• catches DeviceNotAvailable in the cpal error callback and raises a lost flag, so start/write return Err and RecoveringSink can reconnect;
• bounds every queue wait (wait_decision): a stalled or removed device surfaces as a SinkError after 2 s (write) / 500 ms (stop drain) instead of hanging;
• opens the cpal stream on its own thread (streams are not Send on WASAPI) with a 5 s open timeout, and an unopenable device becomes an UnavailableSink whose failure reaches RecoveringSink as an error instead of a panic.

Testing

• cargo fmt --all
• cargo clippy --no-default-features --features telemetry,tui -- -D warnings
• cargo test --no-default-features --features telemetry,tui
• Physically unplugging and plugging my headset on a Windows box.

Additional notes

Screenshots

Previously, this mess would happen. The error would just get outputted in the middle of the TUI, and simply pressing spacebar would not make the song continue.

After, it's slightly more dignified.

Similar Problem on Another Platform

Linux-musl builds are also not covered by this PR. their target-specific dependencies select the fork's RodioSink, so they retain the same output-device hang. The fix belongs in the fork, or Linux-musl can switch to this sink in a later PR.

DO NOT EXPECT CHANGES FOR LINUX-GNU, LINUX-MUSL, OR MACOS USERS

Linux-musl is explicitly called out above because it still uses the fork's sink; Linux-gnu and macOS use their existing platform-specific audio paths.

Walkthrough

Windows streaming builds now select a rodio-backed project sink when no audio backend is specified. The sink opens an output device, reports device-loss errors, and bounds waits for stream opening and queued audio. Explicit backend names and non-Windows builds continue to use librespot lookup.

Changes: Windows audio playback

Layer / File(s)	Summary
Sink setup and queue policy Cargo.toml, src/infra/player/mod.rs, src/infra/player/sink_wait.rs, src/infra/player/sink.rs	The Windows-targeted rodio dependency and module wiring support the sink. The queue-wait policy returns decisions for queue completion, device loss, and stalled progress. Tests cover these outcomes.
Device opening and playback src/infra/player/sink.rs	The sink selects an output device and configuration, then opens the stream on a dedicated thread with a five-second limit. If opening fails, the factory returns an unavailable sink whose start and write methods return errors. start and write report device loss. write waits while the queue exceeds 26 buffers and errors if it makes no progress for two seconds. stop waits up to 500 ms for the queue to drain before pausing. Tests cover unavailable-device startup and an ignored default-device case.
Windows backend selection src/infra/player/streaming.rs, CHANGELOG.md, AGENTS.md, src/infra/player/AGENTS.md	When no backend is specified on Windows, backend resolution selects the project sink. Explicit backend names and non-Windows platforms continue to use librespot lookup. The changelog describes Windows output-device recovery and the environment variable for selecting the built-in backend. The guidance documents the sink’s Windows scope and recovery behavior.

Merge Risk: Minimal · up to 50bd4

This change replaces the Windows streaming audio output with a sink that detects unplugged devices and bounds its waits, so playback should no longer freeze when a headset is removed. No blocking issues were found in the supplied material. Remaining limitations, such as the unchanged Linux-musl behavior and the lack of recovery when the system default device changes, are documented.

Explanation

The title uses the conventional-commit prefix "fix" with the scope "player", which matches the repo's accepted prefixes. It describes the main change: a Windows-specific sink that prevents playback stalls after output-device changes. The objectives confirm that the PR replaces the Windows rodio sink with SpotatuiSink, adds bounded queue waits, and handles device loss through RecoveringSink. The title is concise and imperative.

Move device lookup and config queries inside the timed open thread.

OPEN_TIMEOUT covers only the wait for the spawned thread. Before that, SpotatuiSink::open runs these calls on the calling thread, which is librespot's player thread via RecoveringSink::start:

• default_host
• output_devices
• default_output_device
• default_output_config
• supported_output_configs

These calls query the audio endpoint service. If that service stalls, they block with no bound. This is the same hang class the PR removes for write and stop.

The code already moves device into the thread, so Device is Send. Move the whole open sequence into the thread closure. Send Result<Player, String> back as before. The existing recv_timeout then bounds the full open.

Also applies to: 213-215

Windows builds without streaming now compile rodio and cpal.

This entry is non-optional. The slim build (--no-default-features --features telemetry,tui) and the headless build (--no-default-features --features telemetry) on Windows therefore compile rodio with the playback feature, which pulls in cpal. Only src/infra/player/sink.rs uses this entry, and src/infra/player/mod.rs compiles that file only with streaming.

Consider making the Windows entry optional = true and activating it from the streaming feature. Check first that this does not enable rodio default features on Linux and macOS. If it does, keep the current layout and document the cost in the comment above the entry.

Based on learnings: flag Cargo.toml dependencies that introduce unnecessary crates or features.

Clippy fails on Windows: sink.rs:7 needs one more space of indent (doc_lazy_continuation), and no PR leg builds Windows. In the CHANGELOG, the backend override is SPOTATUI_STREAMING_AUDIO_BACKEND, not a config.yml key, and playback resumes on the new device when you press play, not on its own.

[2570165831]

Thanks, the hang analysis matches the fork's RodioSink, and bounding each wait so RecoveringSink gets an Err is the right shape. The two points from the last review are fixed. A few more:

• sink.rs:5-7: the module doc lost a closing parenthesis, and the summary sentence ended up in the third bullet: "(a dead device never drains" has no ), and "This sink stays silent, …" now reads as part of the stop bullet. Close the parenthesis and move that sentence into its own paragraph below the list.
• The root AGENTS.md (Alternative sources) says src/infra/audio/player.rs is "the only file where rodio types appear". sink.rs is now a second one, so that line, and src/infra/player/AGENTS.md for the new sink, need a note.
• The comment added to the audio-decode rodio entry ends with "Slim and streaming-only builds do not compile it." The new Windows entry is not optional, so on Windows every build compiles rodio and cpal, slim and headless included. Keeping it non-optional is probably simplest (an optional entry wired to streaming would turn on the default-feature rodio on Linux and macOS too), but the comment should say Windows is the exception.
• linux-musl builds also use the fork's RodioSink ([target.'cfg(...)'] picks rodio there), so they keep the same hang. Not for this PR, but the fix in the fork, or a later switch of musl to this sink, would cover them. Worth a line in Additional notes so it is not lost.
• sink.rs is gated on target_os = "windows", so no CI job runs its seven tests: the Linux legs never compile the file, and the Windows desktop job runs only the shell's tests. wait_decision and WaitDecision are plain logic; moving them out of the Windows gate (or into a small ungated module) would let the Linux legs run those tests.
• with_sample_format(sample_format(format)) asks the device for librespot's output format (S16 by default), but this sink hands rodio f32 samples and rodio converts for the device. WASAPI shared mode usually only offers its f32 mix format, so the first open may fail every time and open_sink_or_fallback does the real work. Dropping with_sample_format and letting rodio pick from the device config may be simpler. Can you check which config the debug log shows on your box?
• The summary says switching outputs also hung. lost is set only on DeviceNotAvailable; when Windows changes the default output while the old device stays present, WASAPI keeps playing on the old device and nothing here moves the stream. If that case is out of scope, the CHANGELOG's "unplugged or changed" could say "unplugged".

[LargeModGames]

Two doc fixes and two accuracy fixes left. sink.rs:5-7 misses the ) after "never drains" and the summary runs into the stop bullet. AGENTS.md:449 still says audio/player.rs is the only rodio file. The Cargo.toml comment on the rodio entry is wrong for Windows slim builds now. And lost only trips on DeviceNotAvailable, so the CHANGELOG should say "unplugged" unless you handle a default-device switch too.

[Oud-Idk]

@LargeModGames @2570165831 (this message covers both)

That's a lotta comments! Anyway, here are some things I want to share:

• AGENTS.md and src/infra/player/AGENTS.md now accounts for the WIndows sink.
• Cargo.tml now clarifies the Windows dependency cost.
• Added the Linux-musl limitation to Additional notes.
• Moved WaitDecision, wait_decision, and their tests to sink_wait.rs, so the Linux streaming tests can run them.
  • The Windows-specific one remains separate.
• CHANGELOG.md says "unplugged" rather than "unplugged or changed", as switching to default isn't handled.
• I tested the suggested config change, but it produced distorted audio due to sample mismatch on my box, so... don’t think this change is safe without a more complete investigation of rodio's sample conversion path.

[LargeModGames]

The main merge put the old #984 and #985 entries back at the top of ### Fixed in CHANGELOG.md (lines 13-14). Main already has newer versions of both further down, so please drop those two lines. Windows clippy and the player tests pass here.
