For displaying subtitles with audio files, add the audio resource to a
<video> tag and the subtitles inside it in a <track> tag. The audio element
has no visual display, so it can't display subtitles.

I don't know how you managed to get Opera to display subtitles from <track>
below the video, but that sounds like a Opera bug.

That sounds like browser bugs. Do register bugs on browser where it doesn't
work. Remember to provide full examples of what doesn't work - what you
have provided here can't be used to replicate the bug. You should add at
least the HTML markup that you're using.
