I use Krita on two systems (one Debian with XFCE, one Arch with OpenBox).

Krita sometimes shows a "warning" dialog (for example, when closing Krita without saving the current project), accompanied by a sound effect. I couldn't find any setting in Krita to disable this sound. Any thoughts on what I'm missing?

For Krita 2.x, that's probably defined in the KDE system settings. In 3.0, Krita uses the default Qt message boxes which shouldn't make a sound.

Would there be an easy way to disable it without installing all of KDE? If not, I'll just try to ignore the sound until I switch to 3.0. Good to know it's solved there.

You could probably hack up the right config file, but right now I wouldn't know which one
