Music and Movement synchronization

Hello everyone. I have problem with synchronization start music and movement my player om way. On different decices i have different FPS and music and movement player have unsynchronization.
Move and start MusicPlay im use in FiixedUpdate. And multiplier for move player its step update fixedTime.
In Init game i set FPS = 30. How i can synchronizate music and move on different divases. tnanks for help

Code (CSharp):

1. float fixedDTime = 0.02f;
2. void Update()
3.     {
4.      
5.         if (!GameController.Instance.isGameStart)
6.         {
7.             if(Input.GetMouseButtonDown(0))
8.             {
9.                 GameController.Instance.GameStartAction();
10.             }
11.             return;
12.         }
13.      
14.         // смена направления движения
15.         if (Input.GetMouseButtonDown(0) && canClick)
16.         {
17.             click = !click;
18.             if (click)
19.             {
20.                 direction = X_Dir.Direction;
21.             }
22.             else
23.             {
24.                 direction = Z_Dir.Direction;
25.             }
26.         }
27.      
28.  
29.     }
30.  
31.     private void CustomUpd()
32.     {
33.         if (canClick) // обычное движение
34.         {
35.             print(fixedDTime * playerSpeed);
36.             transform.Translate(direction * fixedDTime * playerSpeed);
37.         }
38.         else
39.         { // полет над бездной
40.             transform.position = Vector3.MoveTowards(transform.position, flyDestination, Time.fixedDeltaTime * playerSpeed*1.38f);
41.             if (Vector3.Distance(transform.position, flyDestination) == 0)
42.             {
43.                 canClick = true;
44.             }
45.         }
46.     }
47.  
48.     // Update is called once per frame
49.     void FixedUpdate()
50.     {
51.         if (!GameController.Instance.isGameStart) return;
52.  
53.         if (Time.time - timeMusic > 1f && !isMusicStart)
54.         {
55.             isMusicStart = true;
56.             GameController.Instance.PlayMusic();
57.         }
58.         //print("TimeStart " + timeStart + "====== Time " + Time.time);
59.         if (timeStart < Time.time)
60.         {
61.             timeStart += fixedDTime;
62.             CustomUpd();
63.         }
64.     }
65.  
66.  
67.  
68.  

 

I recommend a coroutine or, if you are using an animation, try animation events. They can play sounds etc at certain points in the animation. Animation events support any method that returns void and has one parameter. Beware that the animation event seems to search the component the Animation component is on for the method you provide. Also as far as I know animation events are heavy on the CPU because they use some kind of weird CPU expensive C# feature to find the method.
