ViPER4Android not processing

Question

After a couple of times of trying many solutions I found on the internet, I still couldn't fix the problem. I think, I have tried almost everything.

---

Actually, before this problem, I also have one more problem, which is now fixed. That problem is that the Driver Status is "Abnormal", and the Audio Format is "Unsupported", like this:

Driver Version: 2.5.0.4
NEON Enabled: No
Enabled: No
Status: Abnormal
Audio Format: Unsupported
Processing: No
Sampling Rate: 0

Well, that problem is fixed now (solution here), but I still got a problem.

ViPER4Android is not processing, even if I'm playing a song. I'm pretty sure that the music player that I'm using is supported. I am using Google Play Music as my music player.

The problem is that, whatever I change (a setting) on ViPER4Android, it is still the same. It doesn't do anything, but the stock equalizer does. The stock equalizer is still working, which should be not.

Here is the driver status:

Driver Status: 2.5.0.4
NEON Enabled: Yes
Enabled: Yes
Status: Normal
Audio Format: Supported
Processing: No
Sampling Rate: 48000

Answer 1

The issue is found on "audio_effects.conf", which contains unnecessary things that needs to be removed and some to be changed, in order for it to worked.

For Samsung devices, "audio_effects.conf" is found in /system/etc.

Remove these:

Libraries:

output_session_processing {
  path /vendor/lib/libLifevibes_lvverx.so
}

mysound {
  path /system/lib/libmysound.so
}

myspace {
  path /system/lib/soundfx/libmyspace.so
}

soundalive {
  path /system/lib/libaudiosa.so
}

soundalive_sec {
  path /system/lib/soundfx/libaudiosaplus_sec.so
}

soundbooster_plus {
  path /system/lib/libsamsungSoundbooster_plus.so
}

Effects:

soundalive {
  library soundalive_sec
  uuid cf65eb39-ce2f-48a8-a903-ceb818c06745
}

lmfv {
  library output_session_processing

fens {

soundbooster_plus {
  library soundbooster_plus
  uuid 50de45f0-5d4c-11e5-a837-0800200c9a66

Output Session Processing:

output_session_processing {

  }

  ring {
      sa3d {}
  }

  voice_call {
      fens {}
      lmfv {}
  }

  sec_voice_communication {
      fens {}
      lmfv {}
  }
}

Change these:

Libraries:

From:

pre_processing {
  path /vendor/lib/libLifevibes_lvvetx.so
}

To:

pre_processing {
  path /system/lib/soundfx/libaudiopreprocessing.so
}

Effects:

From:

bassboost {
  library soundalive
  uuid a926a540-418a-11e1-b2f1-0002a5d5c51b
}

To:

bassboost {
  library bundle
  uuid 8631f300-72e2-11df-b57e-0002a5d5c51b
}

From:

virtualizer {
  library soundalive
  uuid c747f6a0-418a-11e1-a621-0002a5d5c51b
}

To:

virtualizer {
  library bundle
  uuid 1d4033c0-8557-11df-9f2d-0002a5d5c51b
}

From:

equalizer {
  library soundalive
  uuid c117b70-f97f-11e0-be50-0002a5d5c51b
}

To:

equalizer {
  library bundle
  uuid ce772f20-847d-11df-bb17-0002a5d5c51b
}

For Samsung devices, after doing those things above, also copy the modified "audio_effects.conf" to /system/vendor/etc.
