* Fixed `DirectSoundOut` failing every playback with `DirectSoundException 0x80004001` (or an `ArgumentException` for a format with extra data, e.g. one read from a WAV by `WaveFileReader`): the secondary buffer's `WAVEFORMATEX` was still a GCHandle-pinned `WaveFormat` instance — a site missed in the #1432 marshalling conversion, since `WaveFormat` no longer carries `[StructLayout]` — and now marshals via `WaveFormat.MarshalToPtr` * Fixed `WasapiPlayer` and `WasapiOut` being stranded in the `Playing` state, unable to play again, when the source's `Read` threw or the source ended before the first buffer was filled (#1442) * **macOS support (preview)** - A new wrappers library is added wrapping macOS native API's for playback/recording, reading/writing files and resampling audio. The `NAudio.MacOS` package ships pre-release only (`X.Y.Z-preview.N`) while its API settles, so it stays pre-release alongside stable releases of the other packages. Special thanks to @mdcdi1315 (#1325) for the work and the tests. For more information, see the [design](Docs/Architecture/MacOSWrappersDesign.md) doc that describes the decisions that helped shape the wrappers. (#1398) * **VB.NET support** - Added `SampleProviderBase` and `WaveProviderBase`, base classes that keep the NAudio 2 `Read(buffer, offset, count)` signature for languages that cannot name a `Span<T>` in a method signature, and a [Using NAudio from VB.NET](Docs/UsingNAudioFromVB.md) guide covering playback, recording and custom providers from VB (#1426)
