Movie Texture Audio is Silent

Question

I am using a Movie Texture (.mov format), and Unity is extracting the Audio Clip from it automatically. It does so successfully, to extra an Audio Clip that is of the correct duration. However, it is totally silent (no volume at all).

Issue: Audio Clip extracted by Unity from my .MOV file is Silent.

(it is NOT silent when played in QuickTime)

Question: Why? How can I fix this?

Are you sure that you set up the playback correctly, and that the audio clip is added to an Audio Source in the scene? Does it play audio if you play the movie in the inspector preview?

If not, then you should probably file a bug, and attach the movie file to the bug report, so we can have a look at it.

In the Editor Preview -- it is silent there as well. I have solved my problem by exporting the audio clip separately to ogg format. Although it is a bit annoying, it works, so for us, problem is "resolved enough".

I solved this adding an audio source to the gameobject that had the movie texture. After that I took the sound file that unity imported from the movie and added it as the audio for the audio source. To test it I wrote:

 void Start () {
     MovieTexture temp = (MovieTexture) renderer.material.mainTexture;
     temp.Play();
     audio.Play();
 }

And it worked.

I was having this problem too, I was using script to set the clip to the audio source. I had to call .Play on the audio source as well as the movie texture.
