I can't seem to find any existing post that addresses my issue.
I published a Storyline course for the Web and included HTML5 compatibility. When I view the same course on IE, Chrome, Firefox and Safari, I have drastically different experiences. The most troubling is that my Firefox course does not have any audio.
First, are you testing the content after it has been uploaded to a web server or LMS? Or are you viewing it locally after publishing it?
Second, it may simply have to do with HTML5. Different browsers handle HTML5 differently. To get a better understanding of the way different browsers handle HTML5, you may want to take a look at this page in the different browsers you're using.
For example, with Google Chrome my audio score is 20 with +5 bonus points. In Firefox, it's slightly lover and doesn't support MP3 or ACC for HTML5.
If you have the course uploaded to a server, are you able to share a link? I could do some browser testing and let you know if I experience the same issue with the audio. If you don't have the course uploaded, are you able to share the project's .STORY file here?
As Christine mentioned, Firefox doesn't currently support MP3 playback in HTML5 output. It's a known issue in Firefox and they do have plans to implement it in the future:
The course has been uploaded to Tempshare and that's what I'm viewing it from. It sounds like you've answered my question though, in that Firefox does not currently support MP3 playback in HTML5 output. Is there another way to publish my course that uses something other than MP3?
Curious if there've been any updates related to the audio playback problem in Firefox? The Bugzilla history shows that work has been done on this issue, but still no audio.
Are you trying to view the HTML5 output in Firefox? Or just standard Flash output where the mp3 files are not playing as expected? We don't support the viewing of HTML5 output in Firefox, so you'll want to use one of the supported browsers detailed here.

Hi Kevin,
I don't have any updates to share, but you'll also see in our viewing requirements that the HTML5 content is supported in Chrome and Safari.
Any updates on this? I also have a course where the audio files are mp3 format and won't play in firefox.
