BackgroundMusic VS autorandr

For controlling a software defined volume like Windows has, try https://github.com/kyleneideck/BackgroundMusic

Download Background Music: LINK (free and open-source) Once downloaded, run it and you'll see it as an icon in your menu bar

Thanks for the comment. I checked out Rogue Amoeba's SoundSource, and BackgroundMusic. I think they're using some sort of virtual audio device or something to intercept applications' audio data, control each application's volume, and then send it to the speakers (or another output device).

I had an app called Background Music that I deleted a few days ago, but it still shows up as an audio output in the Sound menu bar menu as well as in Settings.

you can check BackgroundMusic : https://github.com/kyleneideck/BackgroundMusic

Tried https://github.com/kyleneideck/BackgroundMusic before. But didn't work for me.

could use the postswitch hook provided by autorandr, though this would require letting autorandr manage your display layout as well: https://github.com/phillipberndt/autorandr

autorandr worked great for me for hot plugging when I would frequently use my laptop with two external monitors.

Autorandr does run in the background as it is a daemon. For systemd integration see https://github.com/phillipberndt/autorandr/blob/master/contrib/systemd/autorandr.service

I use autorandr (https://github.com/phillipberndt/autorandr) to load display configurations with a hotkey. I'm 100% sure there is a "better" way of doing so over my setup.

If your using X11, try autorandr. It's a bit clunky for me with the windows moving around after waking up but they eventually find where they're supposed to be... mostly.

I would suggest taking a look at something like autorandr to help dynamically adjust your settings when you connect/disconnect.

There's also autorandr that allows you to save monitor setups and automatically switch between them as you connect/disconnect displays

No, but you can save settings to script and run on login. Arandr does it with GUI. Autorandr automates and manages multiple setups.
