AudioSource attached to VideoPlayer produces choppy sound when playing certain mp4 files with VideoPlayer created from script

Video

-

To reproduce:

1.Download and open attached project.
2.Open "scene1" Scene.
3.Select "Plane" object.
4.Add "Games for Windows" video to Average Color From Texture(script) component's "Video To Play" slot.
5.Play the scene and notice choppy sound in the video.

Expected result: Sound is played smoothly without any audio artifacts.
Actual result: Sound is played with choppy sound in the background.

Reproduced with: 5.6.0f1, 2017.1.0a2, 2017.1.0a5.

Notes: This happens only with certain videos. There are 4 mp4 files in the project. With "toystory" mp4 file choppy sound does not appear. However, with "Games For Windows" and with "3 Ninjas Kick Back (USA)" mp4 file background sound is present. Also, If VideoPlayer and AudioSource Components are added to object manually audio artifacts are heard much less than when instantiating them from script.

    Maybe the video's framerate isn't equal the Unity's framerate. So, I've fixed with this:

    Application.targetFrameRate = (int)GetComponent<UnityEngine.Video.VideoPlayer>().frameRate;
