Audio does not resume when user resumes course in LMS

Do you get the black screen with the play button?

No. When I return to the course, it automatically starts playing without the audio. If I click stop and then click play, the audio starts playing again.

Do you have it set to force resume? Also one last question at the beginning did you do anything to prevent the Play button from appearing? 

It sounds like the Play button or resume dialogue is not appearing which mean that the audio will not play because it has not been instigated by the user

I have not created any triggers for this course. I just published it to LMS. When I stop the course, my LMS tells me it is in progress. When I try to resume the course, I get:

If the training doesn't load, click here to open it.

I click the link and it resumes from where I left off (sans audio). The play button turns into the pause button since it starts playing automatically.

which variant of resume do you use in storyline?

• Prompt to resume
• Always resume

It is set to always resume.

I have tested "always resume" with Storyline 3.77

• on the first start (first slide has audio) -> big play button appears -> click -> audio is playing
• stop the course on slide with audio
• resume the course -> the big play button appears again -> click -> audio is playing

if there is no play or resume button before the slides with audio starts, the autoplay of audio is blocked by modern browser (until the first user click)

Which version of Storyline you have used to publish the course?

I am using the same version you show in your image. Here is my index file.

try: change the resume setting to "Prompt to resume"

do you have audio on resume?

We see the same issue.

We have Resume set to "Always resume" . If the learner leaves the module, then comes back into the module, you cannot hear the audio. If you click on the seekbar, or click a button on the screen, then the audio can be heard again.

If we change the Resume option to Prompt to Resume then audio works fine once you resume the module.  But if the option is set to "Always Resume" then the audio does not work until you click something on the screen.

We see this now in both Modern and Classic players. We see it in older modules that did not have a problem before.

My guess is it has to do with a change in Browser functionality that Articulate will need to address.
