Direct mp4 plays fine on Chromium, seems like a HLS.js issue.

Console logs the following:

Or a mismatch in codec info in the .m3u8 as mentioned in #5234.

Hello,

I think hls.js doesn't initialize correctly the audio source buffer because we specify opus instead of Opus. See the original issue on their repository: video-dev/hls.js#4527

Changing it to Opus prevents playback on firefox and chrome.

Doesn't look like there is an easy solution to this problem though.. may have to stick with AAC.

Serving other .m3u8 selectively based on the User-Agent string maybe.
