Oh dear! Buenchico's advice that worked so well since last May, seems to have been overtaken by another problem just as Christmas is approaching and no sound comes through.
I am trying something different now with a Christmas carols site by first uploading separately a folder containing the MIDI (music) files, conveniently named. Then re-upload the amended carols site which now includes links to the MIDI files. It means clicking a link on each page and will show the Windows Media Player, but this can be minimised and/or stopped as wished before going on to the next page (or over-ridden by clicking the link on the next page). Presumably you would need to have Windows Media Player installed on your PC for this to work.
Try a visit to this URL and see what happens:
