Question

JavaScript => public static function Reset(config: AudioConfiguration): bool;
C# => public static bool Reset(AudioConfiguration config);

Parameters 参数

config

The new configuration to be used. 使用新的配置。

Returns 返回

bool True if all settings could be successfully applied.

如果所有的设置成功应用，返回true。

Description 描述

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.

执行修改设备配置。针对AudioSettings.OnAudioConfigurationChanged委托参数deviceWasChanged=false被调用。它不能保证所指定的设置可以使用，但尝试使用系统支持的最接近的值。

JavaScript:

#pragma strict
public class TestAudioConfiguration extends MonoBehaviour {
	function Start() {
		AudioSettings.OnAudioConfigurationChanged += OnAudioConfigurationChanged;
	}
	function OnAudioConfigurationChanged(deviceWasChanged: boolean) {
		Debug.Log(deviceWasChanged ? "Device was changed" : "Reset was called");
		if (deviceWasChanged) {
			var config: var = AudioSettings.GetConfiguration();
			config.dspBufferSize = 64;
			AudioSettings.Reset(config);
		}
		GetComponent.<AudioSource>().Play();
	}
	static var validSpeakerModes: int[] = [intAudioSpeakerMode.Mono, intAudioSpeakerMode.Stereo, intAudioSpeakerMode.Quad, intAudioSpeakerMode.Surround, intAudioSpeakerMode.Mode5point1, intAudioSpeakerMode.Mode7point1];
