jplayer module not working

The module lists jplayer module as working, but it doesn't. I fixed the issue of it not being visible (?) with this patch:

     );
     
     $players['jplayer_module']=array(
-      'path' => '',
+    'path' => module_exists('jplayer') ? drupal_get_path('module', 'jplayer') . '/jplayer.module' : '',
       'name' => 'jPlayer Module',
       'download_link' => 'http://drupal.org/project/jplayer',
       'filetypes' => array('mp3', 'm4a', 'oga', 'webma', 'wav'),

but when you then view a node with an audio field you'll see:

Warning: call_user_func() expects parameter 1 to be a valid callback, function 'audiofield_jplayer_module' not found or invalid function name in audiofield_get_player() (line 128 of sites/all/modules/audiofield/audiofield.module).

So not sure why jplayer module is listed, if it is not supported/working against the latest jplayer module.
