So, while working out I dropped my phone about a foot and a half on to a padded gym floor. Now it won't play any of the audio from youtube videos, during the default music app, the winamp app, or any of the audio touch tones. For whatever reason I can listen to the audio if I use the AlarmDroid App. Ringtones and the tone that plays when adjusting volume also function properly. Anyone have any idea as to what I did and how to fix it?
