I installed the Acroread package and it installed ok, but when I click on the sound file icon I now get a pop up box from Acrobat telling me I need to install a player. When I click the"ok" button to do so, I get a web page telling me
We're sorry, but the third-party media player required to play the selected media file in your Adobe PDF document isn't available for your system. No media player will be downloaded at this time.
It then lists a bunch of media player download sites (Flash, Quicktime, Realplayer, WMP).
This is exactly what happened when I tried this in MINT. In that case, I went a step further and installed Realplayer, but that made no difference (Acrobat Reader has a 'preferred media player' setting which is set to Realplayer by default and can't be changed !).
