audio isn’t playing at a retry in “repetition” mode for Dialog Cards in Course Presentation

Dear H5P Community,

I wonder if anyone has faced the following issue and knows how to go around it. 

When you apply the repetition mode in Dialog Cards activity in the Course Presentation the audio files added to the activity are not playing upon the second attempt (retry). The audio files are not playing upon taking the second round too. 

The advantages of the “repetition mode” are that this mode offers rounds (attempts) and the self-evaluation checkmark whether you get the dialog card “right” or “wrong”. If you checked some of the dialog cards wrong it will offer you another round upon completion of all the dialog cards.

When you attempt another round the audio files won’t play. This is a problem for a seamless practice of dialog cards that have audio files added to them.  

We are using a recently updated Moodle 3.6.3 version. I tested whether the audio files are playing in three browsers: Chrome, Safari, and Firefox on a desktop computer. It played in neither of them. 

Your assistance will be highly appreciated. 

Regards,

Sabina
