Hello mylim，

Hello mylim,

我测试  设备枚举和配对示例。它可以列出我的两个USB耳机：

I test the Device enumeration and pairing sample on Raspberry Pi. It can list my two USB Headsets like this:

您可以尝试查看它是否适用于您的2个USB音频适配器。

You can have a try to see if it works for your 2 USB audio adapters.

例如，关于保存应用设置，您可以在
StopWatcher（）：

About save app settings, for example, you can add the following code piece in StopWatcher():

            Windows.Storage.ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;

            if (ResultCollection != null)
            {
                foreach (var device in ResultCollection)
                {
                    var deviceInfo = device.DeviceInformation;

                    localSettings.Values[deviceInfo.Name] = deviceInfo.Id;
                }
            }

如果我有一些误解或您有任何疑虑，请随意让我。

If I have some misunderstanding or you have any concern, feel free let me.

祝你好运，
