Mind you, we're not only talking about the sounds here.

Yes, I think I noticed that, and it seems a logical place to provide that kind 
of integration (and also efficient to provide a central "hub" for integration 
with the host).

I guess there must be a generic Qt beep that one can tap into to replace beep, 
but for the others I really have no idea. OS X has a limited set of notification 
sounds of its own, but here too applications (or application frameworks) that 
provide their own set of notification types provide their own mechanism to 
configure these (if at all).

There's a sound for emptying the host trash, but I have never seen it among the 
options for the system beep as far as I can remember. The KDE trash is stored in 
the host trash, but in such a way that it can be emptied independently (emptying 
the host trash also empties KDE's trash, by contrast). Given that distinction I 
would find it confusing to use the same sound for both empty actions.

I honestly don't know. Sounds used for notifications that have a native 
counterpart could use the native default sound by default (or the one configured 
if it's feasible to obtain that information). But what about notifications that 
are specific to KDE and that use specific notification sounds? It seems more than 
reasonable to use that KDE sound. Even more so than with look and feel that will 
be beneficial for cross-platform users. After all alert sound specificity is 
supposed to aid in determining what's going on and how to react. If there was no 
point in that we'd still be using simple beeps for everything.

At the moment I can only think of a few examples. Adium, a multi-protocol IM 
client that is a native port of pidgin. It provides its own customisable sound 
themes rather than using system sounds and notification settings. More or less 
commercial IM/VOIP applications like Skype and Viber provide the same sounds on 
all platforms where they exist, at least for their specific events.

Where and how exactly are the default sounds configured?
