Hello everyone,

I'm working on a nice professionnal project since a couple of week. Everything was going fine, it was playing a background video and music, it worked on iPhone. I actually have an old build with all these working.

But suddenly, after a couple of little updates unrelated to audio/video, these stopped working on the iPhone. With remote preview or on the server, they just don't play no more.

So I did a minimal project with just a webm video + webm sound to sort it out. They are triggered by a first tap button. Nothing happens on the iPhone.

Note : the sound demo projects included in C3 (audio FX, positionned audio) don't have sound anymore on my iPhone either. I don't know if they were they supposed to work before. I updated my iPhone (iPhone SE 2020, not old) but it's not better.

I don't understand at all.

If anyone is kind enough to check this minimal project, you can get it here :

and tell me if "audio effects" and "positionned audio" are supposed to work on iPhone. So maybe it's my iPhone even if there arent any reason for that ...

Thanks !

Even just to check if it's just my iphone or everyone.

Thanks

Well I did find a fix by adding a H.264 source to the video object, with a mp4 video.

And the iphone plays that one.

And now the sound is back.

Very strange. Maybe the webm video has a wrong codec and it make the whole sound fail.

So I can move on and the problem is fixed for my project.

Still something disturbing : any other C3 project still run without sound on Iphone (those from the C3 website)

Example : I make a new project, audio object, tap object, import a mp3 converted into webm. Play the audio on tap : no sound on iPhone. No errors in console.
