Click on the first timelapse vid to the left. Prettyphoto opens (not auto play) and without clicking play, soundtrack will start. This is due to a second lightbox behind the prettyphoto. (Click X at the bottom left of the Prettyphoto screen and you’ll see the smaller lightbox).
I have disabled all switches relating to the Responsive Lightbox to no avail. I have also left blank the PrettyPhoto optional link in the Portfolio area of the theme (this results in the video not loading at all). At this point I am stumped… any help would be appreciated.
