And you only ever listen to one thing at a time, from one program at a time, and all audio content ever has its loudness perfectly normalized to a global standard everyone adheres to.

This and notification volume is generally set separately.

You seem to have taken a sarcastic comment seriously; in particular, this part is obviously not true:

> all audio content ever has its loudness perfectly normalized to a global standard everyone adheres to.

There is truth in the statement. Hate to break it to you volumes are not uniform even for single sources.

I don't want to adjust my system volume to change the volume of an over-loud video. My system volume is set for my comfort so my notifications and other applications are the right volume.

A volume slider on a video player is a really basic feature that every one should have.

Set for your comfort doing what exactly? You're basically just prioritizing one source of media over another As TeMPOraL has pointed out you only listen to one thing at a time. Notifications etc. also have their own separate volume settings generally.

> As TeMPOraL has pointed out you only listen to one thing at a time

Maybe you and TeMPOraL do.

Not to mention, maybe a long-running process will use some audio cue as a notification while you're listening.

(Actually, given the rest of the comment, I'm pretty sure TeMPOraL was being sarcastic.)

Audio ducking is a big thing these days and becoming more and more prevalent. All phones do it.

Or, like how I use it, normalizing different sites that have different baseline volumes, so I don't have to keep changing my system volume.

I take it you don't watch content on your tv or your phone or tablet.

Most things these days, good or bad, are not designed for power users.

Ironically many here I'm sure are running MacOS.
