URL: https://learning.edx.org

Browser / Version: Firefox 141.0
Operating System: Windows 10
Tested Another Browser: Yes Chrome

Problem type: Video or audio doesn't play
Description: The video or audio does not play
Steps to Reproduce:
On https://courses.edx.org/ some lessons have an audio player at the top of the page, but it doesn't work. It is implemented with a standard element. So I can find the audio and play it in another tab but not directly in the website.

In Firefox (tested with no extensions, fresh profile, audio/video permissions allowed), the audio player displays, but does not load or play the file. It does not even make a request for the file in the Network tab. But it works well in Chrome.
