'Play With Me - 4' uses sound when turning the pages. Since you seem to
have no sound card installed that's a bit of a problem. I don't think that
returning true on a missing hardware is a good idea. Rather than this I'd
like to add a flag 'disableSounds' to Preferences and modifying some
method appropriately (see below).

Hope this helps,
  Andreas
