Get the full name of the sound device from Windows

Question

Is there a way to get the name of the sound device full in Windows XP and later?

I can use MIXERCAPS, but the szPname member will contain 32 characters (including NULL). For the name of the Microphone (High Definition Audio Unit) audio device, I will return only Auditor High Audence. This is because MAXPNAMELEN is defined as 32. I tried to redefine it to a larger number without effect.

Here is the code I'm using:

MIXERCAPS mc;
ZeroMemory( &mc, sizeof(MIXERCAPS) );
mm = mixerGetDevCaps( reinterpret_cast<UINT_PTR>(m_hMixer), &mc, sizeof(MIXERCAPS) );

I saw this question , but it refers to Vista and later.

BOOL CALLBACK EnumCallback(LPGUID guid, LPCSTR descr, LPCSTR modname, LPVOID ctx)
{
    std::vector<std::string> *names = (std::vector<std::string>*)ctx;
    names->push_back(std::string(descr));
    return TRUE;
}

int main()
{
    std::vector<std::string> names;
    if (!FAILED(DirectSoundEnumerate(&EnumCallback, &names)))
    {
        // do stuff
    }
}
