class ControlServer

Defined at line 29 of file ../../src/media/audio/services/device_registry/control_server.h

FIDL server for fuchsia_audio_device/Control. Claims a Device and makes "mutable" calls on it.

Public Methods

void OnShutdown (fidl::UnbindInfo info)

Called when the client shuts down first.

void DeviceDroppedRingBuffer (ElementId element_id)

Called when Device drops its RingBuffer FIDL. Tell RingBufferServer and drop our reference.

uint64_t count ()

Static object count, for debugging purposes.

void PlugStateIsChanged (const fuchsia_audio_device::PlugState & new_plug_state, zx::time plug_change_time)

This is only here because ControlNotify includes the methods from ObserverNotify. ControlServer

doesn't have a role to play in plug state changes, nor a client hanging-get to complete.

void ElementStateIsChanged (ElementId element_id, fuchsia_hardware_audio_signalprocessing::ElementState element_state)

Defined at line 820 of file ../../src/media/audio/services/device_registry/control_server.cc

void DelayInfoIsChanged (ElementId element_id, const fuchsia_audio_device::DelayInfo & )

We receive delay values for the first time during the configuration process. Once we have these

values, we can calculate the required ring-buffer size and request the VMO.

void DaiFormatIsChanged (ElementId element_id, const std::optional<fuchsia_hardware_audio::DaiFormat> & dai_format, const std::optional<fuchsia_hardware_audio::CodecFormatInfo> & codec_format_info)

If `dai_format` contains no value, no DaiFormat is set. The Device might be newly-initialized,

or `Reset` may have been called. `SetDaiFormat` must be called.

Defined at line 322 of file ../../src/media/audio/services/device_registry/control_server.cc

void DaiFormatIsNotChanged (ElementId element_id, const fuchsia_hardware_audio::DaiFormat & dai_format, fuchsia_audio_device::ControlSetDaiFormatError error)

SetDaiFormat did NOT result in a change to the controlled device's DaiFormat.
