There seems to be an issue with the preloading of audio assets (mp3 and wav) when using Firefox 91 and up on MacOS (tried on several recent MacOS versions)
I gave it a try on a Macbook pro running Big Sur, and the example project worked both on an older Firefox version (85.0) and on the latest. Didn’t get stuck or anything.
Are you seeing any errors in the console while that happens?
I am not getting any errors in the console. The loading progresses normally until it gets to the audio assets, then no more 'progress; events, no ‘start’ event.
If I uncheck the “preload” option on all audio assets, then the loader completes normally.
This issue occurs for all our projects, when testing using BrowserStack.com. All MacOS versions and Firefox V91 and up.
I’m wondering if this might have to do with recent security changes. A couple of my projects failed to load if I accessed the launch page directly from a new window instead of from the editor. This particular project does seem to put out the same errors in the console if I access it via incognito window and then sign in:
Again, not sure if related, but this was new to me this morning. Basis, Ammo, and Platform.js all errored out in the same way on my projects. Maybe it does the same for media assets? I haven’t tried it since all of mine live in a separate S3 bucket.
