Icon for Walkman in lockscreen does not work/ missing

[cagrvc]

Since the last 4.3 update of my XperiaZ, the icon for Walkman isn't working anymore in my lockscreen. Whenever I play music it just shows the time clock when it should be the song currently playing in the background. Before, I'll just open the screen and press the next/stop/previous button, now I had to unlock it for me to enable to press the next/stop/previous button. I already tried to restart my phone but still nothing happens. Anyone who has the same problem with me? What should I do?

Do you have smart key app?

Remove it and it should be fine.

Also,you could try to disable only music in smart key app.
