With this sample minimal output and debug on error switched on i get this 
output:

Debugger entered--Lisp error: (error "Don't know how to play track: (*track* 
(type . file) (name . myfile.mp3))")
  signal(error ("Don't know how to play track: (*track* (type . file) (name . 
myfile.mp3))"))
  error("Don't know how to play track: %s" (*track* (type . file) (name . 
"myfile.mp3")))
  (if (not player) (error "Don't know how to play track: %s" track) (funcall 
(emms-player-get player ...) track) (setq emms-player-playing-p player 
emms-player-paused-p nil) (run-hooks (quote emms-player-started-hook)))
  (let ((player ...)) (if (not player) (error "Don't know how to play track: 
%s" track) (funcall ... track) (setq emms-player-playing-p player 
emms-player-paused-p nil) (run-hooks ...)))
  (if emms-player-playing-p (error "A player is already playing") (let (...) 
(if ... ... ... ... ...)))
  emms-player-start((*track* (type . file) (name . "myfile.mp3")))
  (if emms-player-playing-p nil (emms-player-start 
(emms-playlist-current-selected-track)))
  (unless emms-player-playing-p (emms-player-start 
(emms-playlist-current-selected-track)))
  emms-start()
  emms-source-play(emms-source-file "myfile.mp3")
  emms-play-file("myfile.mp3")
* call-interactively(emms-play-file)
  execute-extended-command(nil)
* call-interactively(execute-extended-command)

I get this "Dont know how to play..." error no matter which version or setup in 
my .emacs
I use.
