I haven't had a problem with anything except for the volume of my audio playback. Whenever I listen to music, I've noticed a majority of the songs have drastically decreased in volume. What was normally 50% in volume is now 95/100%. A few songs (such as the first one I select in a playlist) revert back to normal volume, but then everything else is very quiet. Same thing for calls and videos. Any idea on how I can fix this?
