[GUIDE] Tentative fix for FB Messenger, Whatsapp, etc, low volume notifications

Some of you may have noticed that some apps notifications start up at very very low volume (like whatsapp and facebook messenger). This was driving me crazy, but I think I found a way to disable this behaviour without semmingly ill effects.

If you test this, pls give me your feedback.

This should work in every ROM. Viper installer zips floating around change this specific file, so I don't know it it works with Viper installed.

TUTORIAL


Open /system/vendor/audio_effects.conf and COMMENT OUT these lines:

Code:

---

ring_helper {
    library mot_speaker_helper
    uuid bce61ec2-eca4-445c-9dcb-91cc7cce01ad
  }
  notification_helper {
    library mot_speaker_helper
    uuid bce61ec2-eca4-445c-9dcb-91cc7cce01ae
  }

---

and

Code:

---

ring {
        ring_helper { }
    }

---

and finally

Code:

---

  notification {
        notification_helper { }
    }

---

Save and, for good measure, also copy this audio_effects.conf over the one in /system/etc/. This is because I don't know which one is the system reading. Maybe this is optional, but I didn't test it without copying the file.

Works for me.

Ringtones still ramp-up, but that I don't care.
