This issue is in v1.5.16 too. We'll have to cherry-pick the fix in patch/v1.5.x and cut a patch as this should work in the latest stable release as well.

Cherry-picked into patch/v1.5.x. If this build (https://github.com/video-dev/hls.js/runs/31691495472) fixes the issue for v1.5.16, we'll tag it as patch v1.5.17.

@matvp91 does selection work correctly for you at this preview URL?

All good. 👍

Thanks @matvp91! This release is for you: https://github.com/video-dev/hls.js/releases/tag/v1.5.17

Pro-tip: setAudioOption accepts track object references as input (for a fast or direct match):
hls.setAudioOption(hls.allAudioTracks[0])
