使用USB麦克风时USB Soundcard音质不佳 [英] USB Soundcard bad sound quality when using USB microphone

问题描述

您好，

我在Dragonboard 410c上运行最新版本的Windows IoT Core（10月更新）。现在我已将USB麦克风连接到Dragonboard，还有USB声卡，我只使用3.5mm输出。在powershell上将默认的渲染
设备设置为USB声卡，将默认捕​​获设备设置为USB麦克风。现在的问题是，大多数时候我的声音质量非常差，在播放时（听起来像机器人）。当我将默认捕获设备设置为USB声卡时，
一切正常，声音质量很好。

那么这个奇怪的问题又是什么呢？

最好的问候

解决方案

Hello  andy-dev，

我的USB耳机（Logitech USB Headset H340）和官方样本无法重现您的问题  网络摄像头应用示例因为
我无法在Raspberry Pi和Dragonboard上使用版本17763获得录音。在Raspberry Pi录制文件都是噪音但在Dragonboard上它什么都不记录。

所以你介意分享你的代码示例和USB麦克风设备信息吗？所以我们可以进一步调查。

祝你好运，

Rita

Hello,

I'm running the latest version of Windows IoT Core (october update) on a Dragonboard 410c. Now i have connected an USB microphone to the Dragonboard, and also a USB soundcard, from which i only use the 3.5mm output. On the powershell is set the default render device to the USB soundcard, and the default capture device to the USB microphone. Now the issue is, that most of the time i get very poor sound quality, when playing something (it sounds like a robot). When i set the default capture device to the USB soundcard, everything is playing fine, the sound quality is great.

So what could this weird issue be?

Best Regards

解决方案

Hello andy-dev,

I can't reproduce your issue with my USB headset(Logitech USB Headset H340) and official sample Webcam App Sample because I can't get the audio recording works for me either on Raspberry Pi and Dragonboard with version 17763. On Raspberry Pi the recording file are all noise but on Dragonboard it can record nothing.

So do you mind sharing your code sample and your USB microphone device information? So we can do the further investigation.

Best regards,

Rita
