Revdep-rebuild isn't perfect, but it seems unlikely that re-emerging 
some KDE package would fix the problem.  Trying won't hurt though.  
Give kxkb, kdelibs, ksmserver and kcminit a shot.

The keys are defined in /usr/share/X11/xkb/symbols/inet, in my case in
the section 'xkb_symbols "inspiron"'. This maps the extra keys on my
laptop to XF86* key codes.

Then, in the control center, select the function for which you want to
assign a shortcut, press the button under "Shortcut for selected
action", and press the key you want to assign. This assigns one of the
XF86* key codes as a shortcut.

I already did kdelibs without success, but I'll do the others today as
well. Thanks for the suggestion.

The thing that I find really strange is that the key are recognized,
they just don't work as shortcuts.

Thanks.

Yes, but as I said: there are no multimedia-related actions like 
Play or Stop or Mute there, just windowing, editing and navigating 
stuff.  Do I need to emerge a certain KDE component for multimedia 
actions to appear?  Or do they come with a certain player, like 
kplayer or kmplayer?

What happens if you reassign the same shortcuts?  Maybe first back 
up ~/.kde, and if it works, check what's different.

Yes, please read what I write: I do have these keys, they do produce 
the correct XF86* events, and I can assign these events to actions 
such as "Run Command" or "Switch to Next Desktop".  There are just 
no actions like "Play", "Volume Down" or "Mute" that I could assign 
XF86AudioPlay, XF86AudioLowerVolume or XF86AudioMute to.  Where, 
under what tab, under what heading do you have those actions?

Weird.  Maybe you need to run ahead and upgrade to 3.5.3?  3.5.[0-2] 
are known to be quite buggy.

See below for some vague suggestions.  Meanwhile I've figured out 
how to create actions such as "Mute" and "Volume Up" and assign 
them shortcuts.  It's done in the Control Center under Regional > 
Input Actions.  First press New Group.  If the group appears where 
you don't want it, drag it to before Examples, it will then appear 
as a top-level group at the end.  Then in that group create a New 
Action, give it a name, like "Mute", and select the Action type as 
Keyboard Shortcut -> Command/URL.  Then go to the Keyboard Shortcut 
tab and assign it a shortcut, like XF86AudioMute. Then go to 
Command/URL Settings and fill in the related command, like "dcop 
kmix Mixer0 toggleMute 0".  Press Apply.  And so on for other 
actions.

Then it is most likely related.  Maybe the numbers changed, the 
codes that X assigns to XF86AudioPlay and such?  An extract from 
xev for some of the extra keys on my Logitech keyboard (this is for 
Xorg 6.8, which I'm still using, so you might be able to check 
whether in Xorg 7.0 the keysyms changed):

    keycode 178 (keysym 0x1008ff18, XF86HomePage),
    keycode 160 (keysym 0x1008ff12, XF86AudioMute),
    keycode 174 (keysym 0x1008ff11, XF86AudioLowerVolume),
    keycode 176 (keysym 0x1008ff13, XF86AudioRaiseVolume),

But maybe KDE is looking in the old place /usr/lib/X11 for keyboard 
files, which for Xorg 7.0 moved to /usr/share/X11.  It might be 
trying to read /usr/lib/X11/XKeysymDB but not find it.  You could 
try a symlink: ln -s ../../share/X11/XKeysymDB /usr/lib/X11/
Or maybe link to ../share/X11 the entire /usr/lib/X11

I didn't have to do anything to get those working, except make sure kmix
is loaded on login. It seems that it automatically interpreted the
volume controls correctly. And if I remember correctly, even if kmix
was't loaded, it was loaded by the first volume keypress.

Strangely enough, the volume keys have continued working after the
upgrade to xorg-x11 7.0.

The following work with kmix:

keycode 160 (keysym 0x1008ff12, XF86AudioMute)
keycode 174 (keysym 0x1008ff11, XF86AudioLowerVolume)
keycode 176 (keysym 0x1008ff13, XF86AudioRaiseVolume)

The following don't work as shortcuts:

keycode 162 (keysym 0x1008ff14, XF86AudioPlay)
keycode 164 (keysym 0x1008ff15, XF86AudioStop)
keycode 144 (keysym 0x1008ff16, XF86AudioPrev)
keycode 153 (keysym 0x1008ff17, XF86AudioNext)

Thanks for your suggestions. I'll try tonight.

Hmm, maybe nowadays KMix comes with its global shortcuts predefined, 
here they were unset.  When I now set them (and disabled the Input 
Actions), they didn't work at first: logging out and back in was 
required.

Which application should catch them?  You've set them as Global 
Shortcuts in that app?  If you've done so and it still doesn't work, 
try grepping through ~/.kde for XF86AudioStop and such: maybe they 
are doubly defined somewhere.  When still without luck, these 
threads might give you some new idea:

http://forums.gentoo.org/viewtopic-t-442372.html
http://forums.gentoo.org/viewtopic-t-461748.html

Oh, and what do you have set in the Section "InputDevice" 
in /etc/X11/xorg.conf ?

Did that, but could only find one definition for each. Setting the
symlinks you suggested in your previous message didn't help either.

I'll have a look at them, but that will be the last try. The problem is
not important enough to justify spending so much of your and my time on
it. I'll just assign alternative shortcuts using the Windows key.

> Oh, and what do you have set in the Section "InputDevice"

Section "InputDevice"

    Identifier  "Keyboard0"
    Driver      "kbd"
    Option "AutoRepeat" "250 30"
    Option "XkbModel"   "inspiron"
    Option "XkbLayout"  "ch(fr)"

EndSection

Thank you Benno for your time and patience, but if the threads above
don't help, I'll stop trying.

It was worth my time: I now have working volume keys.  :)  I had 
never bothered to find out how to make them work, as I seldom play 
music.  This was a nice occasion.

I still think that in your case there must be some double definition 
somewhere: when I had doubly defined a key, it stopped working 
altogether, performing neither of the two functions.  A single 
definition and logging back in was required to make it work again.
