- **AAudio**: `supported_input_configs` and `supported_output_configs` now return an error for
direction-mismatched devices (e.g. querying input configs on an output-only device) instead of
silently returning an empty list.
- **ALSA**: Device disconnection now stops the stream with `StreamError::DeviceNotAvailable` instead of looping.
- **ALSA**: Polling errors trigger underrun recovery instead of looping.
- **ALSA**: Try to resume from hardware after a system suspend.
- **ASIO**: `Device::driver`, `asio_streams`, and `current_callback_flag` are no longer `pub`.

### Fixed

- Reintroduce `audio_thread_priority` feature.
- Fix numeric overflows in calls to create `StreamInstant` in ASIO, CoreAudio and JACK.
- **ALSA**: Fix capture stream hanging or spinning on overruns.
- **ALSA**: Fix spurious timestamp errors during stream startup.
- **ALSA**: Fix spurious timeout errors during polling.
- **ALSA**: Fix rare panics when dropping the stream is interrupted.
- **ASIO**: Fix enumeration returning only the first device when using `collect`.
- **Emscripten**: Fix build failure introduced by newer `wasm-bindgen` versions.
