I get error when I open Gnome Alsa Mixer:
An error occurred while loading or saving configuration information for GNOME ALSA Mixer. Some of your configuration settings may not work properly.

Bad key or directory name: "/apps/gnome-alsamixer/display_mixers/": Key/directory may not end with a slash '/'
Bad key or directory name: "/apps/gnome-alsamixer/display_names/": Key/directory may not end with a slash '/'

Where to look for /apps/gnome-alsamixer/display_mixers/ ?

Linux Mint Mate 19.1 32bit

Where is /apps/gnome-alsamixer/display_mixers/ supposed to be?

I don't use GEE`NOME, but it has to be some config file somewhere,

Being GEE'NOME they may have overridden it and used one of there own. worse case you can grep your system in places where GEE'NOME and Alsa resides to look for the phrase it is speaking about.

where the path is up to you to put where you want it to search. Then edit the file and see if that fixes it. as Most configs and PATH statements don't use the end / the "bug" maybe reported to the proper authorities. If you want to.

If I am not mistake, by default, Linux Mint uses pulseaudio, not alsa, but I could be wrong...
