Audio media in choices

@barbaraT , @machadi FYI, this has been identified as a regression: audio on choice list options is not currently working in Enketo, although it continues to work correctly in KoboCollect.

Audio choice lists appears to be a relatively little used feature, so we are unsure of when this regression might have crept in; best I can determine it was working back in 2014! But if this is something that you have been using successfully more recently, then please let me know as it might help us narrow down what caused it to stop working and when.

I’ve posted a workaround, of sorts, in response a more recent post about this same issue: MP3 audio in select_multiple choices not visible on Kobo web forms - #3 by Xiphware
