I had the same problem and solved implementing a PlayerListener and deallocating sounds after play:

  playbackPlayer = Manager.createPlayer(ttsConnection.getFileUrl());
  PlayerListener pl = new PlayerListener() {

      public void playerUpdate(Player player, String event, Object eventData) {
          if (event.equalsIgnoreCase(PlayerListener.END_OF_MEDIA)
                  || event.equalsIgnoreCase(PlayerListener.STOPPED)) {
              player.close();
          }

      }
  };
  playbackPlayer.addPlayerListener(pl);

Cause :

Many devices have limits of how many sounds can be in the prefetched state at once.This differ with devices. On many S60s, for example, it's six ,on many other devices, it is only one.

Possible Solutions :

Realize the players, but don't prefetch them - they'll be prefetched automatically when they play.
use a PlayerListener to deallocate the players after they play, to avoid holding too many in the prefetched state.
