I bought an HTC One X and when I first started using it whenever I played audio I would have a little red Beats Audio icon shown in my notification bar. When you pulled the bar down it would list the item and say "Beats Audio enabled" and when you touched it, it would turn it off and on.
Recently it seems to have stopped being displayed. This is on all audio, so music from the htc music app, Youtube, and Deezer (a music streaming app).
Does anyone have any ideas on what's happened to it, if it's a known bug or if there is an obtuse setting hidden somewhere that I can try to see if I've turned it off by accident.
I have had a poke through the settings and can't see anything obvious. I am running TasKiller but I would assume that running an audio app would kick off the app.
