Parámetros

Valor de retorno

bool True if all settings could be successfully applied.

Descripción

Performs a change of the device configuration. In response to this the AudioSettings.OnAudioConfigurationChanged delegate is invoked with the argument deviceWasChanged=false. It cannot be guaranteed that the exact settings specified can be used, but the an attempt is made to use the closest match supported by the system.
