Debian, XFCE, System Sounds, and my slow descent into hell.

So, theoretically, to enable system sound effects in XFCE, you do the following:
Settings, Appearance, Settings, and toggling the two checkboxes under "Event sounds"

So heres what I went through:
These toggles initially did nothing. This is because XFCE only really
seems to support this feature because its running GTK. Usually you'd install a library like libcaberra to fix this.

Heres the funny thing. On my system, installing libcaberra did not automatically load the module. I had to write a conf file into the Xsession.d folder myself to get the module to load. I don't know if this was a freak accident but it took me 2 hours of random wild goose chases before I figured out what I needed to search and do.

Also libcaberra doesn't support all possible event sounds in gtk, and ive seen multiple forum threads mention the possibility its just unmaintained in general which...????
