Audio tag on ios 7 not showing progress-bar and volume control.

[Control-C]

My code works on ios 6 (* iPhone 4 / 5 ipod )

But on ios 7 it won't work

Using this example code: http://explodedview.co/demo/audio-player/

    <source src="audio/Experience_English.mp3" type="audio/mpeg">

[Control-C]

Ok found the bug

Problem is in the meta tag is used:
meta name=" viewport" content="user-scalable=0, initial-scale=1.0 " (* for the screen size )

By adding this in the css its works !!!

audio { width: 300px; display: block; margin:20px; }
