Seek not working #71

Hey Soundcloud-team!

For the current version of the JS API the seek function does not seem to work.

my code:

SC.stream('/tracks/52693751').then(function(player){
    player.seek(5000);
    player.play();
});

As far as I see it this should make the song start at the 5 seconds position but it just plays from the beginning...
Am I doing something wrong here?
