Question RegisterHandler() not calling Method, problem where?

Hello, I'm making a multiplayer game in Unity with Mirror networking system. Note that Mirror not server-client, it's with host-client system based.
I'm trying to make my own network AudioSource as there is no free asset for Mirror in store. I might have something wrong that's not making the method PlayAudioWhenDetect(). Here's my two scripts for the system below:

Code (CSharp):

1. using System;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using Mirror;
6.  
7.  
8. namespace Mirror.NetworkAudio
9. {
10.     public struct AudioTypeNet : NetworkMessage
11.     {
12.         public int content;
13.     }
14.  
15.     public class NetworkAudio : NetworkBehaviour
16.     {
17.         [SerializeField, SyncVar]
18.         public int audioType;
19.  
20.         public void PlayAudio() //Works
21.         {
22.             AudioTypeNet msg = new AudioTypeNet();
23.             msg.content = audioType;
24.             NetworkServer.SendToAll(msg);
25.         }
26.     }
27. }

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Mirror;
5. using Mirror.NetworkAudio;
6. using kcp2k;
7.  
8. public class NetworkAudioRecieveAndPlay : NetworkBehaviour
9. {
10.     void Start()
11.     {
12.         NetworkServer.RegisterHandler<AudioTypeNet>(PlayAudioWhenDetect);
13.     }
14.  
15.     void PlayAudioWhenDetect(NetworkConnection conn, AudioTypeNet msg)
16.     {
17.         Debug.Log("Now networkaudio received message. Time to look for if statement");
18.         if (GetComponent<NetworkAudio>().audioType == msg.content)
19.         {
20.             GetComponent<AudioSource>().Play();
21.             Debug.Log("Played");
22.         }
23.     }
24. }
25.  

I've tested PlayAudio() of NetworkAudio class with Debug.Log(), PlayAudio() works. But the problem maybe with line 12 or 18. I've did a lot of research, but this is my final result. Yet, no errors are shown and the method isn't called. I don't know why .
I've tried googling, youtube searching, documention check etc. Isn't helping. Now Unity Forum might be my last option, hope to get solution, cause otherwise I'll have to give up in this project of a lot handworks. You can ask me for more informations if these scripts can't give any solution.
(I would open source the project, but for some asset's licenses I can't do it, sorry!)

 

Have you tried contacting the people who made Mirror? Most Assets have some sort of customer service which you can contact. I believe they also have an official website and Discord to use to get in touch.

I also believe some people who use Mirror frequent the Multiplayer Unity forum, but contacting the creators directly is still probably your best bet.

 

Yeah, you're right! I was actually unsure too when I was writing this, about the section where I'm writing. Thanks for saying it!
However if you're from future, if trying to get the same thing as I want, you can continue reading here - Edit: Oh no, I was in the wrong forum link!

 

Oh no, am I in correct forum? No way!

 

This is an acceptable forum to have posted this, but I'm under the impression that people who use Mirror frequent the Multiplayer forum more often, so you would probably get better traffic there.
