Hello,
when I listen to music (via headset) or have a call and friends writing something in a chat group or i get a sms I hear an annoying short beep all the time. The IM tone is set to the lowest value. I don't hear any sound if the media player is not running or if I set the "silent" profile. But this is no option for me cause I want to hear if somebody call me.
How can I delete this beep tone?

Sorry for my bad English.
Thanks for helping me. ("power search" could not help me)
