Status: RESOLVED FIXED

Description:
In the Music App, most songs are not visually advancing when played. The music plays fine but the time code remains at 00:00 and the scrubber does not progress along the timeline. If you tap or drag on the timeline the scrubber / toggle will jump momentarily but then reset to the beginning. The time also jumps to the correct code of where you are tapping or dragging the scrubber to but will also reset to 00:00. 
This occurs with Music on Internal and SD
This occurs with headphones or no headphones
This occurs with any of the playlists 

For some reason this is not occurring with every song but I can find no consistency with why it does not reproduce. 

Repro Steps:
1) Update a Flame to 20150513010202
2) Launch Music App
3) Play a song


Actual:
Timeline / Timecode is not progressing


Expected:
Timeline and Timecode will progress to match the song progress
