[emms-help] Error: "Don't know how to play track"

[Jens Juul Christensen]

Hi all

Have spend a lot of time trying to get EMMS working with no luck so far.

First I installed the standard Debian stable version. No matter which setup I 
used 
it gave me the error;

 Don't know how to play track: (*track* (type . file) (name . 
/path/to/some/file/xx.mp3)
 (metadata))


Purged it from my system and tried the version from here:

http://sarg.kollektiv-hamburg.de/~forcer/darcs/emms/

Still I get the "Don't know how to play track..." error. Tried all types of 
setup I could find in
the documentation, in here and Google, all gives the same error.

If I instead try to play a .ogg file I get this error and no music:

save-excursion: Symbol's function definition is void: remove-overlays



This is my current setup:

(add-to-list 'load-path (expand-file-name "~/.myemacs/site/emms"))

(require 'emms-setup)
(emms-devel)

(setq emms-source-file-default-directory "/path/to/mymusic/")

(define-emms-simple-player mplayer-mp3 '(file url)
  "\\.[mM][pP][23]$" "mplayer")

(define-emms-simple-player mplayer-ogg '(file)
  (regexp-opt '(".ogg" ".OGG" ".FLAC" ".flac" )) "mplayer")

(define-emms-simple-player mplayer-playlist '(streamlist)
  "http://"; "mplayer" "-playlist")

(define-emms-simple-player mplayer-apachemp3 '(file url)
  ".m3u" "mplayer" "-playlist")

(define-emms-simple-player mplayer-video '(file url)
  (regexp-opt '(".ogg" ".mp3" ".wav" ".mpg" ".mpeg" ".wmv"
                ".wma" ".mov" ".avi" ".divx" ".ogm" ".asf"
                ".mkv" "http://";)) "mplayer")

(setq emms-player-list '(emms-player-mplayer-mp3
                         emms-player-mplayer-ogg
                         emms-player-mplayer-playlist
                         emms-player-mplayer-video
                         emms-player-mplayer-apachemp3)
)

(setq emms-playlist-buffer-name "*Music*")

(setq emms-info-asynchronously t)

(setq emms-stream-default-action "play")

(defun emms-add-universe-synchronously ()
  (interactive)
  (let ((emms-info-asynchronously nil))
    (emms-add-directory-tree emms-source-file-default-directory)
     (message "Thud!")))


Does EMMS have any system dependencies I have overlooked ?

Im running Debian Sarge and GNU Emacs 21.4. 


Hope someone can help, EMMS seems to fit my needs for a music application 
perfectly...
