Problem with PM notification sound!

[LuciaFilms]

Hello!

I have a slight problem with the PM notification sound, or perhaps with my observational skills? =P

I cannot seem to find the area of the settings to toggle off the PING sound when someone messages you. I frequently listen to music through my speakers while working and no amount of speaker/sound fiddling seems to drop the volume of that ping anywhere below ear-ringingly deafening.
So if anyone would kindly direct my clearly blind self to the correct area in the settings that would be amazingly appreciated.

Thanks in advance!
