更改Windows 10 IoT中的默认音频设备

我在DragonBoard 410c上使用最新的Windows 10 IoT Inisder预览版（Build 15026）并尝试与Cortana交谈。 我已经插入了一个可以与Raspberry Pi（2＆amp; 3）配合使用的USB麦克风，这款麦克风也得到了认可。

但是，在Web门户中，我将这些设备视为默认音频设备： 演讲者：扬声器（适用于Qualcomm SoC的QCAUD实时（WaveRT）驱动器） 麦克风：内置麦克风（适用于Qualcomm SoC的QCAUD实时（WaveRT）驱动程序）

如何切换音频设备以便识别“Hey Cortana”关键字？

更新的答案 我刚刚得知Cortana确实在最新的Insider Preview中。检查是否有默认麦克风的操作系统配置选项后会跟进。

在发行说明中 有关如何设置和配置麦克风工作的说明。向下滚动到 Cortana说明和已知问题 部分。

You need to get one microphone and one speaker connected with your device. On the Device Settings page of Windows Device Portal, check if your microphone and speaker is the one displayed against Speakers and Microphone. Click the Refresh button and make sure the correct peripherals are displayed.

Adjust the volume for both to be in the range 40-70%. (Please make sure Microphone is not 0.0)
