From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do I keep PulseAudio from randomly changing the volume? (feddit.org)

I'm on OpenSuse Tumbleweed (although I'm pretty sure I noticed the behavior on Manjaro, too).

The problem is that the volume of e.g. Firefox gets turned down for no reason. I noticed that a youtube video was quite quiet. I then checkt pavu control and saw that the volume for Firefox was set to 83%. I set it back to 100, but after the pc resumed from standby, it was at 83 again. Sometimes it's enough to just pause the video for it to move the volume back down.

Why is that and how do I disable this functionality?

I've never seen this "just" happen, but have seen it during events like switching from headphones to speakers and such.

You may also have your app volumes linked to your master channels, meaning when you lower the sound on your master with something like a key combo, then it lowers the individual app volumes as well, which is generally not something you'd want enabled.

Apps at full, and using PCM/Master channel for general volume is pretty much the "default".
