Detailed Description

Platform audio controller that manages sinks and microphone capture.

Constructor & Destructor Documentation

~audio_control_t()

virtual platf::audio_control_t::~audio_control_t ( )

virtualdefault

Destroy the audio control.

Reimplemented in platf::audio::audio_control_t.

Member Function Documentation

is_sink_available()

virtual bool platf::audio_control_t::is_sink_available ( const std::string & sink )

pure virtual

Check if the audio sink is available in the system.

Parameters

sink	Sink to be checked.

Returns

True if available, false otherwise.

Implemented in platf::audio::audio_control_t, platf::macos_audio_control_t, and platf::pa::server_t.

microphone()

virtual std::unique_ptr< mic_t > platf::audio_control_t::microphone ( const std::uint8_t * mapping, int channels, std::uint32_t sample_rate, std::uint32_t frame_size, bool continuous, bool host_audio_enabled )

pure virtual

Create a microphone capture stream for the requested layout.

Parameters

mapping	Opus channel mapping table for the requested layout.
channels	Number of audio channels in the stream.
sample_rate	Audio sample rate in hertz.
frame_size	Number of samples captured per audio frame.
continuous	Whether silent audio should continue to be emitted.
host_audio_enabled	Whether host playback should remain enabled during capture.

Returns

Microphone capture object for the requested audio layout.

Implemented in platf::audio::audio_control_t, platf::macos_audio_control_t, and platf::pa::server_t.

set_sink()

virtual int platf::audio_control_t::set_sink ( const std::string & sink )

pure virtual

Update the sink value on the backend.

Parameters

sink	Audio sink name to route or capture.

Returns

Status from updating sink.

Implemented in platf::audio::audio_control_t, platf::macos_audio_control_t, and platf::pa::server_t.

sink_info()

virtual std::optional< sink_t > platf::audio_control_t::sink_info ( )

pure virtual

Query host and virtual sink names available to Sunshine.

Returns

Host and virtual sink names when the backend can report them.

Implemented in platf::audio::audio_control_t, platf::macos_audio_control_t, and platf::pa::server_t.
