Defined at line 24918 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 (boolmuted,floatgain_dbfs,OnGainMuteChangedCallbackcallback)
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.
