Stop notifications from briefly lowering media volume I have an LG G6 running Oreo and whenever media is playing and a notification sound comes through something briefly lowers (not fully muted) my media volume. How can I stop this? I don't want notification sounds to change my media volume.
Updated Answer

I first thought that the OP was asking about modifying the behavior of the sources of the notifications which can be done in with finer levels than before using Notification Categories in Android 8.0 Oreo.

However via the comments, it appears that the OP wants to stop Audio Ducking 
from happening in the media player. Unfortunately this is a feature of the 
media app playing the music itself and requires the developer of the app to configure. See

Original Answer

In Android 8.0 Oreo the App can now have Notification Categories

Check the notification setting screen in:

Settings->Apps &amp; Notification->[App Name]->App Notifications



For the App(s) that are interrupting see if you can either disable sound or adjust the priority to one which suits your needs.
