Turn off ducking for one sound

Auto-ducking is on, but some sounds — like a short notification sound — shouldn’t lower the background music? Turn off ducking for that sound only.

Steps

1. Right-click the sound and hover over Auto-ducking.
2. In the submenu, choose Don’t duck.

From then on the background music isn’t lowered when this sound plays. To undo it, choose Duck automatically in the same place.
