I'm investigating a curious problem with crashing IE11.
Our Environment is a website running in IE11 deployed via Citrix Xenapp to iPads with Citrix Receiver.
IE11 11.0.9600.17631
XenApp 7.6
Windows 2012 R2
Citrix Receiver 5.9.4
iOS 8.1.3
In approx. 10% the cases of opening the website the crash of IE occurs.
The use case is, that we want to play a sound when buttons are pushed.
Investigation
We nailed it down to the html5 audio tag which causes the trouble.So we built two minimal examples for reproducing this failure behaviour.On with plain html5 audio tags and the other with scripted audio elements:
<!-- audio1.html -->
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
</head>
<body>
<audio id="player" controls preload="auto">
<source src="img/sound/beep.mp3" type="audio/mpeg" />
<source src="img/sound/beep.ogg" type="audio/ogg" />
<source src="img/sound/beep.wav" type="audio/wav" />
</audio>
<audio id="player2" controls preload="auto">
<source src="img/sound/beep2.mp3" type="audio/mpeg" />
</audio>
<audio id="player3" controls preload="auto">
<source src="img/sound/beep3.mp3" type="audio/mpeg" />
</audio>
<audio id="player4" controls preload="auto">
<source src="img/sound/beep4.mp3" type="audio/mpeg" />
</audio>
</body>
