Additional documentation
This exposes the base
VZVirtioSoundDeviceOutputStreamConfigurationthrough the Go API without assigning aVZHostAudioOutputStreamSink.The Objective-C constructor already exists in
virtualization_12.m; this change adds the matching Go wrapper, constructor, finalizer, interface assertion, and macOS 12 availability coverage. Existing host-audio input and output constructors are unchanged.Apple documents that the output stream's sink defaults to
niland that omitting a sink suppresses the audio:https://developer.apple.com/documentation/virtualization/vzvirtiosounddeviceoutputstreamconfiguration/sink
This is useful for headless VMs that need to expose a playback device to the guest without depending on or playing through the host's default audio device.
