public static bool Reset(AudioConfiguration config);

Parameters

configThe new configuration to be used.

Returns

bool True if all settings could be successfully applied.

Description

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.
