Question Sound gets distorted when played

Hi folks,

in Unity3D when I try to play sounds of multiple explosions I get weird explosion-sounds, i.e. they sound distorted. I already tried to set the dopplerLevel to zero but that didn't do the trick. I do not get any bugs. Any help, please?

Code (CSharp):

1.  
2. //sets up an array of AudioClips and gets populated via Resources.Load
3. AudioClip[] enemyExplSnds = new AudioClip[7];
4.         for (int i = 0; i < enemyExplSnds.Length; i++) {
5.             enemyExplSnds[i] = Resources.Load("Sound/explosions/enemies/explosion_" + i) as AudioClip;
6.         }
7.  

Code (CSharp):

1.  
2. //this plays random sounds
3. int randomExplSndVal = Random.Range(0, enemyExplSnds.Length);
4.             SoundManager.PlaySFX(enemyExplSnds[randomExplSndVal]);
5.  

Code (CSharp):

1.  
2. //This is the method that plays the sound:
3. public static void PlaySFX(AudioClip sfxClip) {
4. //PlaySFX is the simplest, all we do here is get the SoundManager instance, fetch a new SFXSource and use it to play
5. //the clip before stating the RemoveSFXSource coroutine to clean it up.
6.         SoundManager soundMan = GetInstance();
7.         AudioSource source = soundMan.GetSFXSource();
8.         source.volume = GetSFXVolume ();
9.         source.clip = sfxClip;
10.         source.loop = false;
11.         source.Play();
12.         soundMan.StartCoroutine(soundMan.RemoveSFXSource(source));
13.     }
14.  

Code (CSharp):

1.  
2. //This is the method GetSFXSource:
3. AudioSource GetSFXSource() {
4.         // set up a new sfx sound source for each new sfx clip
5.         AudioSource sfxSource = gameObject.AddComponent<AudioSource>();
6.         sfxSource.loop = false;
7.         sfxSource.playOnAwake = false;
8.         sfxSource.volume = GetSFXVolume();
9.  
10.         if (sfxSources == null) {
11.             sfxSources = new List<AudioSource>();
12.         }
13.  
14.         sfxSources.Add(sfxSource);
15.         return sfxSource;
16.     }
17.  

Code (CSharp):

1.  
2. //This removes the sound:
3. IEnumerator RemoveSFXSource(AudioSource sfxSource) {
4.         yield return new WaitForSeconds(sfxSource.clip.length);
5.         sfxSources.Remove(sfxSource);
6.         Destroy(sfxSource);
7.     }
8.
