If you use Volume+ and Poweramp on your Android device, you might notice that Poweramp seems to wipe out/reset Volume+’s sound effects.* I’ve raised the issue with developers of both apps via Twitter – both are very responsive to users – and now Poweramp has a solution:
@jdrch Volume control is very immature on Android platform. You may try to disable Settings=>Audio Engine=>Advanced=>Direct Volume Control.

As it turns out, that setting was already disabled on stock, unrooted Galaxy Nexus, but enabling it fixed the issue with no further action required. So if you’re experiencing the same, simply toggle that setting and you should be fine.
* Oddly enough, Volume+’s and Android’s audio settings will remain ostensibly unchanged, but you can definitely hear the difference.
