setMuted or setVolume do not work on iPad in MediaElement.js

Question

It appears that neither volume controls nor mute/unmute work on iPad. Did anyone encounter this problem before? Pretty straightforward functionality, no errors, just silent fail.

var player;
$(document).ready(function () {
    player = new MediaElementPlayer('#player', {});
});
function mute() {
    player.setMuted(true)
    //  player.setVolume(0) does not work either on iPad

}
function unmute() {
    player.setMuted(false)
}

HTML:

 <audio id="player" controls="controls">
<source type="audio/mp3" src="intro.mp3" /> </audio>

Answer 1

Nevermind. Since MediaElement.js uses native <audio> controls on iPad, according to Safari HTML5 Audio and Video guide, it is not possible to control HTML5 audio volume via script:

On iOS devices, the audio level is always under the user’s physical control. The volume property is not settable in JavaScript. Reading the volume property always returns 1.

... need to program a workaround for iPads.
