Install DSPManager on a non-CM Rom

I would like to install the app DSPManager from Cyanogenmod on my Nexus 4 running ParanoidAndroid. I grabbed the newest CM and extracted "/system/app/DSPManager.apk" and "/system/lib/soundfx/*" and copied the files onto my phone. I also changed permissions to "rw-r--r--", then I rebooted and could choose the new Equalizer in the Settings (in Sounds). However changed Settings did just apply for the next song (not the currently playing) until I started DSPManager again... What is the proper way to install DSPManager on a non-CM Rom, are there other rom-related things I need to change? How can I get DSPManager to work on my Setup? PS: I use the Apollo Music Player PS2: I'm also open to source changes if necessary, but this might not belong on this site!
