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!
