We have a training for all devices where some page says that you have to rotate when you have PhonePortrait. Thats ok but we want to stop the sound and play it when you rotate. It works inside runmode in Lectora online but not in the SCORM. We also have a action on rotate to pause the sound if its portrait otherwise play. That works well!
Is there someone else that have had the same problem?
So I reproduced your issue with the title you posted here. It seems to be some kind of a timing issue as when I added a 0.6 delay to the OnShowStop action it then stopped the audio in portrait mode. Let me know if that works for you also. Meanwhile I will write this up as a bug.
