Declaration

public static bool Reset(AudioConfiguration config);

Parameters

config The new configuration to be used.

Returns

bool True if all settings could be successfully applied.

Description

Changes the device configuration and invokes the AudioSettings.OnAudioConfigurationChanged delegate with the argument deviceWasChanged=false. There's no guarantee that the exact settings specified are used, but Unity automatically uses the closest match that it supports. Note: This can cause main thread stalls if AudioSettings.Reset is called when objects are loading asynchronously.
