Defined at line 24907 of file fidling/gen/sdk/fidl/fuchsia.media/fuchsia.media/hlcpp/fuchsia/media/cpp/fidl.h

A protocol for watching changes to usage gain settings.

The channel will close when the device is not present.

Public Methods

void ~UsageGainListener ()

void OnGainMuteChanged (bool muted, float gain_dbfs, OnGainMuteChangedCallback callback)

Called immediately on connection and afterward any time

the usage gain setting changes.

Clients must respond to acknowledge the event. Clients that do not acknowledge their

events will eventually be disconnected.

Note: This API does not have mute reporting implemented; `muted` is always false.
