Load audio file from iOS documents folder and play it

Still can not achieve this. Can someone help me? I have file on device, I check it (I download it from network, from dropbox to my document directory). Then I am trying to play it and nothing happens. I need play mp3 and/or wav files. Here is how I am trying to play file:

AudioClip clip1 = (AudioClip) Resources.Load(localFilePath); // localFilePath is path directly to file on device (full path, with "var" folder etc., with file extension)
audioSource.clip = clip1;
audioSource.Play();

Also I try with PlayOneShot - not happens No errors or warnings and no sound.
Thank you for helping!

P.S. Duplicated from Audio thread because no one reply there.

 

Finally fixed by myself. Maybe I help someone in future:

publicIEnumeratorplayFile(stringpathToFile)
{
Debug.Log("Path to doc file = " + "file://" + pathToFile);

WWWaudioLoader = newWWW("file://" + pathToFile);
while( !audioLoader.isDone )
yieldreturnnull;

Debug.Log(audioLoader.GetAudioClip(false).name);
audioSource.clip = audioLoader.GetAudioClip (false);
audioSource.Play();
}

 

But very strange. It crashes on iOs device. Here is crash log:

Maybe someone can help with this?
