It can't reproducible in Chrome of Firefox. Example code: <script> const video = document.createElement('video'); video.src = 'your_audio_file.mp3'; video.loop = true; video.muted = true; const check = () => { setTimeout(check, 1000); console.log(video.currentTime); }; check(); </script> Another example: You can also confirm the problem in https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all by replacing the code with the following. <video muted controls> <source src="your_audio_file.mp3" type="audio/mpeg"> </video> You will see zero duration time on the control panel.
