Storyline 360 courses - audio not playing or very delayed in published output

Hi Everyone,

Has a solution been found for this? I'm having a similar issue. The first slide of the course has a significant delay, the audio doesn't synch with the characters. The audio starts playing when the seekbar reaches about the half-point. I was made aware of this issue because one of my stakeholders had the delay in Review 360. I was able to replicate it on my laptop on Edge, but not on my desktop. I had 3 other individuals test the link and two had delays using Edge. I try Chrome and same issue. I opened a case and was advised to do the following:

If possible, you can also view the Review link using your mobile device. You can email the link to your device for easy testing.

• • The course played with no issues on a mobile device.

Another thing you can try is to restart your computer to refresh your computer.

• • Restarted the laptop and issue still persist.

You can also try a different network if possible.

• • Unable to since I am using my work’s network, which is the network that will be use by employees taking the course.

If there is an app running on the background, that could be using a lot of resources, may also impact the behavior of the animation/synchronization.

• • Checked and there isn’t any.

If the course is intended for LMS or web server, you can publish the project and test it on the target environment.

• • The issue was still present when played on the LMS.

I want to point out that the file is located locally, not on a shared drive. Any suggested solutions are greatly appreciated, thanks!
