Audio Having issues with the microphone not recording anything.

So i'm trying to get the microphone to record and play back sound to me while the game is playing. After a little bit of research I found some code online that does exactly that! But for whatever reason no audio is played back to me no matter what I change, no errors pop up either. If anybody could give me possible recommendations on how to fix this id greatly appreciate it. ill include the code below.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class MicrophoneTest : MonoBehaviour
6. {
7.     AudioClip clip;
8.     AudioSource aud;
9.     private bool micConnected = false;
10.     private int minFreq;
11.     private int maxFreq;
12.  
13.     // Start is called before the first frame update
14.     void Start()
15.     {
16.         if(Microphone.devices.Length <= 0)
17.         {
18.             Debug.LogWarning("Microphone Not Connected!");
19.         }
20.         else
21.         {
22.             micConnected = true;
23.  
24.             Microphone.GetDeviceCaps(null, out minFreq, out maxFreq);
25.  
26.             if(minFreq == 0 && maxFreq == 0)
27.             {
28.                 maxFreq = 44100;
29.             }
30.  
31.             aud = this.GetComponent<AudioSource>();
32.         }
33.     }
34.  
35.     void OnGUI()
36.     {
37.         if(micConnected)
38.         {
39.             if(!Microphone.IsRecording(null))
40.             {
41.                 if (GUI.Button(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 25, 200, 50), "Record"))
42.                 {
43.                     aud.clip = Microphone.Start(null, true, 20, maxFreq);
44.                 }
45.             }
46.             else
47.             {
48.                 if (GUI.Button(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 25, 200, 50), "Stop and Play!"))
49.                 {
50.                     Microphone.End(null); //Stop the audio recording
51.                     aud.Play(); //Playback the recorded audio
52.                 }
53.  
54.                 GUI.Label(new Rect(Screen.width / 2 - 100, Screen.height / 2 + 25, 200, 50), "Recording in progress...");
55.             }
56.         }
57.         else
58.         {
59.             GUI.contentColor = Color.red;
60.             GUI.Label(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 25, 200, 50), "Microphone not connected!");
61.         }
62.     }
