Sony Walkman + Clearaudio+ on 4.3?

Hello guys,

I am looking for the Sony Walkman app with Clearaudio+.
I've tried several mods but every one of them gives me a FC when wanting to enable ClearAudio+.
I have the Nexus 4 and I'm running android 4.3.

Has anyone got a working one for me?

Thanks in advance!
