Every player (MS Mediaplayer, MS Mediacenter, VLC, just name it...) accepts mp3.
The 'speaker', 'volume mixer' and 'playback devices', 'volume control cptions' are no players. These are system parts or options; a player is a program or nowadays an App.
The preferred player is the player that is automatically used when you double-click on an mp3.
Somehow you are on the wrong track.
