I have a rooted Samsung Galaxy Note 4 with CyanogenMod 12.1 (Android 5.1.1), and I want to silence the Emergency Alert (e.g. AMBER Alert) sounds without disabling the alerts entirely. A few places have mentioned deleting a sound file, but I can't find it in /system/media, and absolute paths I've seen are also not present (e.g. /system/media/mms)
I am asking about the built-in Android feature, not the Google Now alerts.
