JUST articulate audio not working - but only on a particular laptop
I've got a case where I published an Articulate 3 story containing videos with audio to "CD" and loaded it onto a USB. I tested the content on my own computer, it runs fine and the audio runs fine.
I passed this USB to a second user and while the content runs, the videos move along, the audio does not play. The audio is working on their laptop is working correctly - email notifications, youtube, audio test all chirping away happily.
I don't have details on the make of their laptop or anything like that, but does anybody have any ideas what could be causing this?
Thanks in advance,
