推荐答案

WinMM API 应该提供您请求的功能.

The WinMM API should provide the functionality that you request.

您将使用 DRVM_MAPPER_PREFERRED_SET 消息，该消息通过 waveOutMessage() 函数发送.

You would use the DRVM_MAPPER_PREFERRED_SET message, which is sent with waveOutMessage() function.

但是，如果您尝试自己发送波形声音，则应查看 WinMM.Net 库.

However, if you are trying to send the waveform sound out yourself, you should look at the WinMM.Net library.
