Play sound on laptop speaker, even if additional speakers are connected (but not listed in device list)

I'd like to play a soundfile from the speakers integrated in the laptop, even if an additional speaker is connected via the headphone jack (but it's not listed in the sound device list).

I've had a look at How can I make the computer beep in C#? and How to beep using PC speaker? and have understood that the beep driver was removed in windows 7.

However, I do not want to use this extremely simple integrated speaker controlled by the removed driver, but the normal one present in most modern laptops.

Unfortunately, when I connect my external speakers, they do not show up as an additional device. When I run this code (using NAudio), I always get just one result, and it's the same whether the external speakers are connected or not:

var enumerator = new MMDeviceEnumerator();
foreach (var endpoint in enumerator.EnumerateAudioEndPoints(DataFlow.Render, DeviceState.Active))
{
    Console.WriteLine(endpoint.FriendlyName);
}

Is it possible to play a sound on the normal laptop speaker, while an external speaker is connected?

Edit:
I don't think my question is a duplicate of Play a sound in a specific device with C# I don't see an additional device when I connect my external speakers, so I guess my laptop doesn't have multiple sound cards (how can I verify?).
The solution from the other question (waveOut.DeviceNumber = deviceNumber;) doesn't work for me neither. When I choose deviceNumber = 0;, the sound comes from my external speaker if it's connected. If I set deviceNumber = 1; (while it's connected) I get a MmException

I see I'm a bit late for the party but i was working on something similar and got to this solution. Hope it helps someone in the future :)

var enumerator = new MMDeviceEnumerator();
IWavePlayer waveOut = new WasapiOut();
foreach (var endpoint in enumerator.EnumerateAudioEndPoints(DataFlow.Render, DeviceState.Active))
{
    if (endpoint.FriendlyName == "Name of the device you want")
    {
        waveOut = new WasapiOut(
            endpoint, AudioClientShareMode.Exclusive, false, 0);

        AudioFileReader wave = new AudioFileReader("Audio Name");

        waveOut.Init(wave);
        waveOut.Play();
        break;
    }
}
