Thanks for checking. It turns out that my theme had the audiojs player embedded in it, although there were no instructions on using it. The developer was of no help, so I decided to take a chance and I deleted every reference to audiojs and then everything started working properly.
One question I have though is that the player wants to preload everything, but if it fails then you see “00:00 / NaN:NaN” for the duration and the file won’t play. If you refresh the page then it might find the file and preload properly.
Is there a way to make it not try to preload the files?
Thanks!
