Audio is breaking on coursera

Sometimes when I watch a course video audio disappears. Sometimes I can come back to the place where the audio disappeared, replay, and the audio is OK, sometimes it just goes on and off all the time. I am using Safari 16.5.1 on macOS Ventura 13.4.1 I do not have this issue on youtube or any other platform, only on coursera. Does anyone have the same problem?

Safari has known issues. Try Chrome or Firefox.
