I recently purchased a few JIRA training courses and the audio doesn't seem to be playing on the videos. I tested the audio out on other websites (news sites, YouTube, etc) and there's no problem there. But when I log into my Atlassian account and begin the training courses, there's no audio. I completed the free courses for JIRA a few weeks ago and had the same problem, but those had captions/ subtitles so at least I knew what was being said in them.
I really hope someone can help me soon, I paid a lot of money for these courses and can only access them for 30 days.
