Could someone please explain the following?

:~> alsaequal
If 'alsaequal' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf alsaequal

And…

:~> cnf alsaequal 
alsaequal: command not found  

:~> sudo zypper in alsaequal

Nothing to do.

Am I missing something?

The difference between a software package name (which you try to install and it seems to be installed already) and the name of an executable you try to run from the shell?

Hi
If you look at the info on the package it’s a plugin which you can configure, not a program…


Vendor         : openSUSE
Installed Size : 69.1 KiB
Installed      : No
Status         : not installed
Source package : alsaequal-0.7.1-2.8.src
Upstream URL   : https://github.com/bassdr/alsaequal
Summary        : Equalizer plugin for ALSA <===

Have a read here how it works: GitHub - bassdr/alsaequal: Alsaequal is a real-time adjustable equalizer plugin for ALSA

Thanks to both of you for the solution.
