Some of the files like click-8.ogg are not played from within Stendhal, but work fine if played in mplayer.
Steps to reproduce:
* get the most recent stendhal CVS client
* start it with -Dstendhal.newsound=true directly behind "java" and before any other parameters
* first the login-harp is played
* then the open bag sound is played
* the login-harp is played
* the open bag sound is not played
