Turn off the sound for notification without turning off the speaker

[knightsamar]

This could be useful in cases like a Zoom call where I want to turn off notifications during the call but still want to hear the person.

I am not sure if the GNOME API makes the sound or the application does and depending on that this issue might or might not be possible to resolve.

Personally, I already have events sound turned off permanently, so I don't need this extension to mess with sound, and would prefer that it does not try to do so at all, because I often need to be able to play music to concentrate—or my work might be video and/or audio editing, for which I need sound, but would still need focus by not having visual notifications.
