how can use Xaudio2 in Unity with ill2cpp

Question

i am using SharpDx.dll & SharpDx.XAudio2.dll in Unity3D.

The dll works fine in the editor. However, when I run the program after building Windows, an error occurs in the initialization part. The error log is as follows and a part of the source code is attached.

Doesn't that dll work on windows base? If not, is there any workaround?

    using UnityEngine;
    using SharpDX.Multimedia;
    using SharpDX.XAudio2;
    using System.IO;
    using System;
    
    XAudio2 xaudio2;
    MasteringVoice masteringVoice;
    
    void Start()
    {
       xaudio2 = new XAudio2(); << Error
       masteringVoice = new MasteringVoice(xaudio2);
    }
