How to find config files for audio apps?

[Ralf Mardorf]

If I want to save config files for audio apps in $HOME, so that I can
restore just those files, instead of a complete $HOME, but I don't know,
if I really know all config files. Is there a command to show me all
files?

I noticed for a non-audio app, that it's easy to forget some
configuration. For Evolution I replaced ~/.local/share/evolution/ to get
what I want, but still something isn't the way as usual. Now I noticed,
that I at least have to replace ~/.config/evolution/ with something that
does include, what I want.

To restore complete audio sessions by shell scripts it's important to
know the config files, since not all apps are able to save and load
to/from an audio partition. Some apps simply store files in $HOME.
