My alarm is not on.. and alarm is set to a ring tone i download... now for sound back i did not install..
did you install any app before this happen, if so uninstall it and reboot the phone and see if the problem has been resolve, some peoples on here had similar problem like this and some have found out it was the alarm and some had found out it was a gapps app they install, soundback, kickback of some sort.
