Sound no correctly in Video Player

I’m trying to put a video on my template but the sound in Android not working properly. Although it is heard, it is distorted and have tried several videos and go perfectly .

What can it be?

What I use for video is:

Code video (first work correctly in browser and android app):

<video id="video1" width="100%" preload="metadata" controls webkit-playsinline>
	    <source type="video/mp4" src="http://www.w3schools.com/html/mov_bbb.mp4"></source>
	    <source type="video/ogg" src="http://www.w3schools.com/html/mov_bbb.ogg"></source>
	    Your browser does not support HTML5 video.
	</video>

Code video (not work correct in Android App :frowning:)

<video id="video1" width="100%" preload="metadata" controls webkit-playsinline>
	    <source type="video/mp4" src="http://bideoak.ahotsak.com/MUD003/mud003_010.mp4"></source>
	    Your browser does not support HTML5 video.
	</video>

In the browser works correctly.

Thanks.

The video is wrong … is recorded in stereo and as mobile phase reproduced in mono is canceled and not heard about that …
