I also changed the path of the swf and js files, from the plugin source file and it worked.
The line numbers should be changed are 162,408,416,420. just change “/wp-content/plugins/audio-player/…” to “/wp-content/plugins/audio-player/audio-player/…”
if you don’t want to play with codes you can easily move the content of the audio-player directory in the audio-player directory, to the audio-player directory.
In the admin screen, when you clicked “Check the plugin version” you can get a message “there is a newer version 1.2.3” but, if you downloaded the plugin from wordpress or the plugin homepage it is wrong you don’t need to update.Because there is a mistake in plugin source file.
