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!

  • DSPManager may be depending on CM specifics hence the settings are not applying...? And yes by the sound of it, you'd need to modify the ROM to cater for that :)

  • Have you removed all the other EQ apps? They might be interfering.

Wouldn't you have to chmod rwx-rx-rx? (IE: 755, execute permissions for all users) so that Android can actually run the DSPManager APK/app? Or is this not the case on Android?

  • Yes it was also chooseable as Music Effects and startable...

Post #8 on this forum has a flashable DSPManager zip file that apparently the user reports worked with Paranoid. If anything, you should also look into flashing Beats Audio which will give you just as good (if not better) equalizer settings.
