Dell MultiMedia Keyboard Volume Control
This webpage contains RPMS that install knob a small daemon which can be used to collect output from the volume knob of the Dell Multimedia USB Keyboard.

Good News
I used the RPMS on several Fedora Core 5 and 6 boxes (both x86_64 and i386).
When rebuild, from the SRPM, you probably want to pass along the flag --define 'dist BLAH'. Changing BLAH to something appropriate (fc4, fc5, rhel4, ...)

NOTES: MPlayer and the Dell Multimedia Keyboard
I found the following useful and probably not entirely obvious. Create an XModmap file like:
keycode 144 = XF86AudioPrev keycode 153 = XF86AudioNext keycode 162 = XF86AudioPlay
Load this config with xmodmap my_xmodmap_config. Now, with XBindkeys installed, create an config file for XBindkeys with the following entries.
# Prev "echo "seek -60" > ~/.mplayer/mplinput" XF86AudioPrev # Next "echo "seek +60" > ~/.mplayer/mplinput" XF86AudioNext # Pause "echo "pause" > ~/.mplayer/mplinput" XF86AudioPlay
Load the XBindkeys config file with xbindkeys -f my_xbindkeys_config. Then create a named pipe mkfifo ~/.mplayer/mplinput and add the following:
input=file=/home/user/.mplayer/mplinput
to your MPlayer config file (~/.mplayer/config). Now as if by magic the Fast-Forward/Rewind and Play buttons will be able to control MPlayer. It is left as an exercise to the reader to automate this process at login or better yet make it available system wide.
