What you can try is by calling the waveInGetNumDevs

The waveInGetNumDevs function returns the number of waveform-audio input devices present in the system.

UINT waveInGetNumDevs(VOID);

Returns the number of devices. A return value of zero means that no devices are present or that an error occurred.

Here is an example:

#include <tchar.h>
#include <windows.h>
#include "mmsystem.h"

#pragma comment(lib, "winmm.lib")

int _tmain( int argc, wchar_t *argv[] )
{
    UINT deviceCount = waveInGetNumDevs();

    if ( deviceCount > 0 )
    {
        for ( int i = 0; i < deviceCount; i++ )
        {
            WAVEINCAPSW waveInCaps;    
            waveInGetDevCapsW( i, &waveInCaps, sizeof( WAVEINCAPS ) );

            //Your code here
        }
    }

    return 0;
}
