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.
