Play sound on a specific device

I am starting work at Csharp, and I am trying to develop using NAudio.I found a code on the NAudio website that gives me the ability to play sound. In my case, I will create three buttons, and each button is connected to an external sound card, when I press the button, I want to hear the sound from the speaker that is associated with my sound card (button 1 refers to sound card 1, ...). Thus, each “play” function should produce sound in a particular device. To ensure performance, it’s not very important to create a “play” function for each button (so for each sound card), and my sound allows me to play sound only in the sound card, please can you help me fix the code ???? ??? It is very important for me.
