Windows Phone音频路由/交换 [英] Windows Phone Audio Routing/Switching

问题描述

我正在开发Windows手机应用程序，但无法找到一种方法将音频从耳机切换到扬声器，反之亦然，正如微软在其官方FM收音机应用中所做的那样。

你好shubham，



你可以使用
AudioRoutingManager.SetAudioEndpoint API（Windows Phone 8.0或更高版本）或
AudioGraphSettings.PrimaryRenderDevice API。

< pre class ="prettyprint"> var audioRoutingManager = AudioRoutingManager.GetDefault（）;
audioRoutingManager.SetAudioEndpoint（AudioRoutingEndpoint.Speakerphone）;

 Windows.Devices.Enumeration.DeviceInformationCollection devices = 
等待Windows.Devices.Enumeration.DeviceInformation.FindAllAsync（Windows.Media.Devices.MediaDevice。 GetAudioRenderSelector（））; 
 //显示UI以允许用户选择设备
 Windows.Devices.Enumeration.DeviceInformation selectedDevice = ShowMyDeviceSelectionUI（devices）; 
 settings.PrimaryRenderDevice = selectedDevice;

Hi shubham,

You could use either AudioRoutingManager.SetAudioEndpoint API for phones (Windows Phone 8.0 or later) or AudioGraphSettings.PrimaryRenderDevice API for all Windows 10 devices.

var audioRoutingManager = AudioRoutingManager.GetDefault();
audioRoutingManager.SetAudioEndpoint(AudioRoutingEndpoint.Speakerphone);

https://blogs.msdn.microsoft.com/matthew_van_eerde/2014/03/17/a-mental-model-for-the-windows-phone-audioroutingmanager-api 

Windows.Devices.Enumeration.DeviceInformationCollection devices =
 await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(Windows.Media.Devices.MediaDevice.GetAudioRenderSelector());
// Show UI to allow the user to select a device
Windows.Devices.Enumeration.DeviceInformation selectedDevice = ShowMyDeviceSelectionUI(devices);
settings.PrimaryRenderDevice = selectedDevice;
