问题描述

你好；
我在C ++音频应用程序上工作，我希望能够枚举所有可用的声卡并选择其中一个来播放我生成的声音
有什么帮助吗? Thanks

any help? thanks

推荐答案

您可以使用DirectX枚举设备(正如Kozlow_Sergey在评论中指出的那样)；

You can use (as pointed out by Kozlow_Sergey in the comments) DirectX to enumerate the devices;

#include <iostream>
#include <stdio.h>
#include <dsound.h>

using namespace std;

#ifdef UNICODE
BOOL CALLBACK DirectSoundEnum(LPGUID guid, LPCWSTR desc, LPCWSTR module, LPVOID context)
{
    wcout << "Device: " << desc << endl;
    return TRUE;
}
#else
BOOL CALLBACK DirectSoundEnum(LPGUID guid, LPCSTR desc, LPCSTR module, LPVOID context)
{
    cout << "Device: " << desc << endl;
    return TRUE;
}
#endif

int main(int argc, char* argv[])
{
    if (DirectSoundEnumerate(DirectSoundEnum, NULL) != DS_OK)
        cerr << "Failed to enumerate sound devices";

    return 0;
}

此摘要要求您链接到 d3dx9.lib 和 dsound.lib (实际上，您可以跳过第一个).

希望这会有所帮助，

This snippet requires that you link against d3dx9.lib and dsound.lib (actually you might be able to skip the first one).

Hope this helps,

如果您不能使用Direct Sound，则可以使用此链接

If you can''t use Direct Sound you can use this link
