My SGS cell headphone's button doesn't work, what should I do? My wired headphones, the ones supplied by samsung with the Galaxy S, button doesn't answer calls, open music player, play a track, or even pause tracks. But when I downloaded the trial version of powerAMP, the button interacted only with the app. What should I do to make it work with the whole android again?

Mind that I'm running samsung's froyo on a rooted galaxy S handset.
According to this thread you aren't alone:


  Poweramp hijacks the headset
  controls(wired &amp; BT) from all my other
  media players... I use headset
  controls with the stock mp3 player,
  pandora, xiialive, &amp; fm radio.. they
  all surrender the headset controls
  when not in use, but when I bring
  poweramp in the mix the headset
  controls only work with poweramp.. I
  went into the headset options in
  poweramp and disabled everything, that
  stops the controls in poweramp, BUT
  doesn't restore the headset controls
  to the other players when I want to
  use them...


but according to the last post by the dev this should fix it assuming you are running latest version (uninstalling would probably restore control as well):


  Not exactly. I've made today a
  workaround I mentioned above - so
  unchecking Headset Buttons option in
  PowerAMP now should properly redirect
  next button presses to other players
  (applies to 2.2 only). This will be
  included in next minor release, coming
  beginning of the next week.
  
  Thanks for the report again.
