Making use of volume control keys

[Michael Goetze <mgoetze@mgoetze.net>]

Hi list,

I've just gotten a new laptop (Dell Latitude E4200), and it has some 
keys for adjusting the volume, which I'd like to configure to work with 
Debian. I'm using the awesome window manager.

They keys already get usefully recognized, as evidenced by the following 
xev output:

KeyPress event, serial 28, synthetic NO, window 0x2800001,
    root 0x109, subw 0x0, time 8996889, (4,158), root:(665,178),
    state 0x0, keycode 122 (keysym 0x1008ff11, XF86AudioLowerVolume), 
same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 28, synthetic NO, window 0x2800001,
    root 0x109, subw 0x0, time 8996972, (4,158), root:(665,178),
    state 0x0, keycode 122 (keysym 0x1008ff11, XF86AudioLowerVolume), 
same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

Now all I need is for them to interface with my sound hardware. :) I 
tried installing pulseaudio and running gnome-volume-control-applet in 
my systray, but it didn't have any effect. (The hotkeys for setting the 
LCD backlight interfaced nicely with the gnome-power-manager applet.)

Please CC me on replies, as I am not subscribed.

Thanks,
Michael
