Feedback console should writeout names of conflicting objects

You can filter the Project view to isolate all objects with a certain component:



I also put together this script that will print them to the console for you:

Code (CSharp):

1. using System.Collections.Generic;
2. using System.Text;
3. using System.Text.RegularExpressions;
4. using UnityEditor;
5. using UnityEngine;
6.  
7. public static class AudioListenerConflictDetector {
8.     enum MonitoringLevel {
9.         Always,
10.         OnEnterPlaymode
11.     }
12.  
13.     static readonly Regex messageRegex = new Regex( "There are \\d+ audio listeners in the scene\\. Please ensure there is always exactly one audio listener in the scene\\." );
14.    
15.     // Change your monitoring level here
16.     // OnEnterPlaymode is more performant for normal cases but will only check when you first click play
17.     static readonly MonitoringLevel monitoringLevel = MonitoringLevel.OnEnterPlaymode;
18.  
19.     [InitializeOnLoadMethod]
20.     static void DetectAudioListeners () {
21.         EditorApplication.playModeStateChanged += OnPlaymodeStateChange;
22.     }
23.  
24.     private static void OnPlaymodeStateChange ( PlayModeStateChange state ) {
25.         if( state == PlayModeStateChange.EnteredPlayMode ) {
26.             if( monitoringLevel == MonitoringLevel.Always ) {
27.                 Application.logMessageReceived += OnLogMessage;
28.             } else {
29.                 PrintAllAudioListeners();
30.             }
31.         } else if( state == PlayModeStateChange.ExitingPlayMode ) {
32.             Application.logMessageReceived -= OnLogMessage;
33.         }
34.     }
35.  
36.     private static void OnLogMessage ( string condition, string stackTrace, LogType type ) {
37.         if( type == LogType.Log ) {
38.             if( messageRegex.IsMatch( condition ) ) {
39.                 PrintAllAudioListeners();
40.             }
41.         }
42.     }
43.  
44.     static void PrintAllAudioListeners () {
45.         var listeners = Object.FindObjectsOfType<AudioListener>();
46.         if( listeners.Length <= 1 ) {
47.             return;
48.         }
49.  
50.         // if you want to get really fancy, you can automatically set the filter when conflicts occur:
51.         //SceneModeUtility.SearchForType( typeof( AudioListener ) );
52.  
53.         var inheritence = new List<string>();
54.  
55.         var sb = new StringBuilder();
56.         sb.AppendLine( "The audio listeners are:" );
57.         foreach( var obj in listeners ) {
58.             inheritence.Clear();
59.             var n = obj.transform;
60.             while( n != null ) {
61.                 inheritence.Add( n.name );
62.                 n = n.parent;
63.             }
64.             inheritence.Reverse();
65.        
66.             sb.Append( "  " ).AppendLine( string.Join( "/", inheritence ) );
67.         }
68.  
69.         Debug.LogError( sb.ToString() );
70.     }
71. }

 

So you detect that string with the regex and add the extra info? Mad respect!
