Imagine this: you are watching a movie or enjoying music at a louder volume when all of a sudden a terrible system notification ruins your experience, perhaps even scaring you. Maybe it was the torrent you started downloading half an hour ago or the daily backup you had running in the background. Annoying, isn’t it? I’m sure this has happened to you more than once before.
But don’t worry! There is a simple solution for you: decrease the volume of those nasty system alerts.
Decreasing the system volume lets you play specific audio/video program at your desired volume without getting bugged up by annoying notification sounds. In this beginner guide, we will show you how to decrease your system volume in Ubuntu 18.04 & 16.04.
