Audio issues Internet Explorer 11 on Windows 7
Sep 06, 2017
Dear e-learning heroes,
We're currently experiencing some issues with our newest e-learning.
Problem description: the e-learning consists of several chapters. When going through the first chapter, everything is working correctly. When picking the second chapter, at some (random) point, suddenly the voice-over audio stops playing. After this point, voice-over audio is playing/not-playing randomly. Images and animations are playing correctly however.
Some other issues we're experiencing: publishing of the e-learning takes about 5-10 hours which is extreme. Even previewing a single slide takes around 5 minutes. I personally think the problem is somewhere in the amount of questions or slides. We now have 1286 slides with 504 questions in 84 question banks. In the publishing progress-screen, the creation of the questions takes up a fairly big amount of time.
The amount of slides is due to the multilingual nature of the project. There are 7 scenes, each with their own language of the project.
The problem only occurs on Internet Explorer 11 on Windows 7. Internet Explorer 11 on Windows 10 has no issues. Chrome also works perfectly. The problem is that our customer has Windows 7 machines and the Internet Explorer browser set as default company standard. So using Chrome is a no-go.
On one hand I know this project is kinda huge and that could be the problem. On the other hand the project plays just fine on IE11 Windows 10 and Chrome so there must be something wrong in terms of streaming / memory usage / cache usage in IE11 on Windows 7.
Hoping that someone maybe has a clue of what this could be.
