Internet Explorer 10 Has No Audio? How Do I Fix?

<font size="5">Internet Explorer 10 Has No Audio? How Do I Fix?</font>

Hi,

My "Construct 2" video game

has no audio on Windows 8 Internet Explorer 10?

(audio works in both Google Chrome and Mozilla FireFox)

Here is the demo:

Here is the project:

Any help would be appreciated.

Thanks!

I ran console in IE10 and it shows this error:

Creating AppCache with manifest: 'http://16bitsoft.com/V2/Files/RocksInSpace_BetaTest1/offline.appcache'.

AppCache Fatal Error

I can't release my game until audio is working in Internet Explorer.

Does anyone know how to fix this?

Hi,

I posted a bug report here:

I tried on two different desktops, same result of no audio in IE10.

Hope this can be fixed!

I've yet to try Windows 8, but I know that IE10 doesn't support the Web Audio API yet. Perhaps that's your problem and you need to repack those sound files (you're probably using ogg, I'd imagine) to some other format.

Since IE10 supports neither Ogg Opus nor Ogg Vorbis and Construct2 doesn't support MP3 (for obvious reasons. Namely, asenine licensing fees), this leaves you with AAC.

When I imported WAV music/sound effects

"Construct 2" converted them to OGG and M4A files.

So there is no way to get audio working on IE10?

That sucks!

M4A actually is AAC (MPEG4-AAC, that is).

Have you tried removing the ogg files?

You have to set the correct mime type for m4a on your server.

How would I do that?

Thanks!

If your server is incorrectly configured, it will not serve AppCache or .m4a files correctly, which will break both offline caching and audio in IE and Safari. This is a problem with your server and not a C2 bug. To fix it make sure .m4a serves with the MIME type audio/mp4, and .appcache serves with text/cache-manifest.

I did this:

but the audio is still not working in IE10?

Did I do something wrong?

Thanks!

Still no audio when game is played on my website using IE10?

Anyone know how to fix that, I tried and failed?

JeZ+Lee

Ya. I just checked it out. Something is indeed broken.

BG Audio definitely doesn't work. SFX does though.

Are you sure all your audio files have been successfully converted to M4A? Perhaps you accidently removed the M4A of your background music.

Try creating a .htaccess file on your server and adding this line:

AddType audio/mp4 m4a

Try creating a .htaccess file on your server and adding this line:

AddType audio/mp4 m4a

Or if .htaccess already exists just add that line to the bottom of it.

The weird thing is: Sound effects do seem to work inside IE. Wouldn't he normally have those stored as M4A, as well?

Without checking the actual file size, I'd also dare say the audio file for the background music is way too big, as it takes approximately 2 minutes to load for me.
