It's not working for me either. It seems to be just the Dictionary that is affected; audio on other pages seems to be working fine.
Additional info: if you look up a word in the Dictionary and then click the audio button, nothing happens. For example, if you look up 'kazan' you see the usual display along with an audio button but, as we've found, clicking the button doesn't play the sound file.
The sound file for 'kazan' appears to be
