canvas: video oral history use case with alternative audio file

[jronallo]

How would I also include an audio file alongside a video? Are all the
items expected to be a video and the same content? Would it be alright
to also add an audio file or two to the items? My use case is that I
have a lot of video oral histories. Since they're mostly talking heads
some may prefer to just listen to the audio than to play the video.
How would I say that this is the audio content for the video?

For now I've just included this in the same list as the video choices.

Use viewingHint of none per IIIF/iiif-av#64 (comment) for any audio that should not be played. Could be in the same annotation body but outside the choice? Still not certain whether this clearly communicates that this is the audio that is from the video rather than some other type of audio.
