Major Storyline Audio Playback Issues
I have recently been receiving a lot of feedback from my course testers that there have been issues with audio not playing, audio only partly playing, incorrect audio playing or layer audio overlapping when they visit the slide initially, however when they return to the slide the audio works as designed.
Even weirder, two people may be testing the exact same package and will experience completely different audio glitches and some testers experience no glitches at all.
These tests have been done on both Review360 and in SCORM 1.2 and 2004 on our LMS. It has been tested in both Edge and Chrome. There are no issues with the timeline and the audio is not attached to any triggers. I've been using Storyline for around a decade now and have never encountered an issue like this.
From looking at the forums here it seems that a number of people are having similar issues, with no solutions provided or any update/explanations as to why this may be occurring.
This is incredibly frustrating, as it means nothing can get past quality control and be provided to clients.
Has anyone experienced this and found a fix?
Hello everyone,
Happy to share that we've just released a new update for Articulate Localization!
In our latest update (June 9, 2026), we've included a fix for:
- After publishing a multi-language project to an LMS, text-to-speech audio in the source language was out of sync.
You'll need to be working with the latest version of Storyline 360 (Update 119) to take advantage of this fix. Launch the Articulate 360 desktop app on your computer, and click the Update button next to Storyline 360. You’ll find our step-by-step instructions here.
Please let me know if you need additional help.

Hi Mateusz, and thank you for all your insight and suggestions. Regarding the "I got a code to paste to index_lms.html", I have no idea where to paste that code. If it involves pasting into the LMS system, I don't have access to my client's LMS.
index_lms.html is in the folder published by Storyline.
Use Gemini or any other free AI tool to help you paste this code properly. It shouldn't do any damage, but if you paste it incorrectly, the course may not work.
My audio is also not playing in preview or when published as a SCROM and accessed via the LMS. I can hear the audio by previewing it from the timeline, but it does not play otherwise. I am using the most recent update for Storyline (6/23/26) and have submitted a support ticket.
Looping back here to say that the update published 7/8/26 fixed the audio import issue from PowerPoint from me and my audio is now working. Thanks, all!
Just adding to the list of people who are affected by this problem. All the same issues including random slides being affected with delayed or no audio, but clearing up if the slide is restarted. The course will often test cleanly in SCORM Cloud, but not on our customer's LMS (SuccessFactors).
While I'm not an expert, many LMSes cache their data for a faster content retrieval.
Even if you have re-exported some audio or video, its name hasn't changed - from the LMS perspective, you didn't change the file, it is probably still cached. Even if Articulate did some tricks to mitigate, your LMS might not even 'read' these tricks, as for it - nothing has changed.
Try clearing the LMS cache also - maybe that's why there's still an issue.Unfortunately, the newest release of Storyline (June 9 2026) did not fix the problem and clearing the cache also did not help.
As of 6/23/2026 after the update, my team is still having audio issues in review 360. We have a round of initial testing for our storyline training. To review content for clarity, before we upload it to the LMS. I have 4 testers for this initial testing, and its a 50/50 split. Two have no issues two are having audio delays on 95% of the slides. When I test I'm not able to get the same audio delay mentioned.
All were assigned the review through the review360 "Request Review" button. They were auto emailed the review link. However after getting the feedback saying there was a delay in audio. I tested by sending then the link directly from the share button. One reported this helped the other reported it didn't make a difference.
I have also republished the training multiple times after the update to see if its still having this issue. (it was)
Affected users are on chrome, both cleared their cache, tried alternative browsers, and are on our office wifi.
Audio is not the text to speech from articulate. Its a mp3 file from published in audition.
I saw someone mention it could be the audio file size? I haven't tested reducing that yet, but I would like to avoid compressing the audio if I can to try and maintain the sound quality.
My concern is what are the chances this audio issue continues in to the LMS/SCORM?
Updated to the new release from 6/9/2026. I'm having the same issues with videos now too. It's affecting all my customers! Please fix asap!!!!!
Hi lorraineS,
Sorry to hear that you're now experiencing video playback issues in Storyline.
Are you seeing this behavior in Review 360, and also when uploaded to your LMS? If this issue is local to your LMS, testing your published output in SCORM Cloud can help confirm if the behavior is LMS-specific. Also, do the videos fail to load across multiple browsers, as DShaw touched on?
If you're comfortable sharing the affected .story file, we're happy to take a closer look and test it on our end. Do you mind uploading a copy here in the discussion or through a support case?
Hello Steven, if you could fix the issue with audio files and that it seems it stems from the common cause, will there also be a fix available for the videos?
I think this is a Chromium engine issue. See the other thread fromDigitalTeach01 from yesterday
Hi, same issue here.
We updated storyline, re-created the SCORM and... now the problem is on the VIDEOS instead of the AUDIO mp3s.
please find attached the error in consolle output. This is giving us MAJOR problems with an important customer. Any solution?

looks like after the update, the problem now affects videos instead of audios
Hi DigitalTeach01,
Sorry to hear that videos from Storyline are not loading in the published output.
I see that you've also opened a support case being handled by my teammate, Mcgem. It looks like he replied to your email with an upload link you can use to share your affected files for testing.
We can continue troubleshooting through your case to keep everything in one spot.
I installed the new version, re-published to Review and it worked without any audio issues. I'll upload to the LMS tomorrow. Fingers crossed!

Hello,
While the sound issues might have been corrected, now videos don't play on iPhone devices (I have iPhone 13).https://360.articulate.com/review/content/321f60f7-24c7-4568-bbf5-8b6d307f493f/review

Hello,
Can we get a short note about what was causing a problem, how to replicate it and how was it solved? So I can test, before releasing, because as multiply stated in this thread - this issue is totally random. I personally experienced it only once, while I got like 20 reports about it from my Reviewers. It's not easily replicable, so it would be great to have an opportunity to actually CHECK if everything works.Hello,
I can confirm that Update 118 solved the issue for us. We just have to republish to a new scorm and upload it in the LMS.
Thanks
I just tested the new release (May 27, 2026 (Build 3.118.37003.0) for 2 of my audio issues. Neither issue is solved.
My issues are with multilanguage files. The timelines of english are getting extended to the length of the spanish audio tracks upon publish
AND the spanish audio playback is overlapping even though it is obviously not on the timelineHi lorraineS,
Sorry to hear that you're struggling with audio playback issue from a Localized Storyline file.
I see that my colleague Genelyn has been helping you in a support case. As she shared, we have this behavior logged as a bug in Storyline Localization. This bug causes:
- The source language Text-to-Speech audio Timeline to change, after publishing a multi-language project to LMS
We've included you in the bug report, so we can update you as soon as a fix is in place. I'm sorry if this has been slowing you down!
Adding on. I'm also having audio issues. Particularly I work with multi language files and the audio is not obeying the timeline at all in non-english languages. Very frustrating. I'm on version
May 12, 2026 (Build 3.117.36909.0), testing in SCORM cloud a scorm 1.2 published multi language package
