cpal 0.18.2

Added

• AAudio: Xruns are now reported as ErrorKind::Xrun.
• CoreAudio: Xruns are now reported as ErrorKind::Xrun.
• PipeWire: Xruns are now reported as ErrorKind::Xrun.
• WASAPI: Capture xruns are now reported as ErrorKind::Xrun.

Changed

• BSD: Clarify that realtime-dbus has no effect there.
• CoreAudio: Bump objc2-core-foundation dependency lower bound to 0.3.1.
• iOS: Timestamps now include hardware latency and update when the audio route changes.
• JACK: Timestamps now include port latency.
• Linux: Clarify that realtime alone is a no-op without realtime-dbus.
• PipeWire: Devices with multiple ports now get distinct, localized, per-port names.
• WASAPI: The windows and windows-core dependencies are now both pinned to 0.62.

Fixed

• Timestamps now stay monotonic across device and graph changes.
• ALSA: A nonzero but sub-millisecond stream timeout is no longer treated as a non-blocking poll.
• ALSA: Fix compilation on FreeBSD, DragonFly, and NetBSD.
• ASIO: Fix duplex streams silently dropping audio when built from separate Device handles.
• AudioWorklet: Fix Stream operations to work when called from any thread.
• AudioWorklet: Fix stale audio output when a data callback wrote a partial buffer.
• CoreAudio: Fix stale audio output when a data callback wrote a partial buffer.
• CoreAudio: Default-output streams now report xrun status.
• iOS: Streams now resume automatically when an audio session interruption ends.
• JACK: Streams with more channels than physical system ports no longer fail to build.
• JACK: Channel enumeration is no longer capped at the physical system port count.
• JACK: Device::id no longer embeds the process ID, so DeviceId is now stable across application restarts.
• PipeWire: Fix streams starting audio before play() is called.
• PipeWire: Fix real-time promotion blocking the audio callback thread on Linux.
• PipeWire: Fix rtkit burst limit errors from repeated real-time promotion on quantum jitter.
• PipeWire: Fix 24-bit sample format mapping.
• PipeWire: Nodes with an /Internal media class are now enumerated as devices.
• PipeWire: Streams for a specific device no longer auto-reroute if it disappears.
• PipeWire: Build on 32-bit targets without native 64-bit atomics.
• PulseAudio: NoData errors are no longer misreported as buffer xruns.
• PulseAudio: Build on 32-bit targets without native 64-bit atomics.
• visionOS: The CoreAudio backend now builds.
• WASAPI: Stream::drop, play, and pause no longer panic when the device is lost.
• WASAPI: Output streams no longer reject formats that the built-in resampler can convert.
• WASAPI: Fix 24-bit samples not being packed into the upper bits of their sample container.
• WASAPI: Reported buffer sizes are no longer off by one frame.
• WASAPI: Default device changes no longer report DeviceChanged, which wrongly implied the stream had rerouted automatically.
• WebAudio: Fix stale audio output when a data callback wrote a partial buffer.
• WebAudio: Fix unsound Send + Sync on Stream when compiled with +atomics.
• WebAudio: Fix Host::is_available() always returning true, even in non-window contexts.
