.opus file not playing in MS Edge while it is supported

[alfureu]

Having a strange issue, I selected in the advanced settings the .opus file conversion. The file from koozic plays in Firefox, but does not plays in MS Edge. However, any other .opus file is supported in Edge, and I can play without any issue, e.g.: https://hpr.dogphilosophy.net/test/index.php

Any idea what might be the issue?

Hello,

The only difference I see in comparison to your example is that the opus file is transcoded on-the-fly in KooZic. That might play a role... However, I'm not sure about this, I'll have to perform a couple of tests to make sure.

I think the issue is that the opus file produced by koozic is hls, while Edge does not support this, only if first the full file is downloaded and then played (like DSub does). Firefox can play hls with opus codec no problem.

Indeed, that's what I meant. I'll run some tests to check this.
