Slackware 14.1 sound buttons
 
Hi,
I can adjust sound by using the G.U.I., but I can't adjust the volume with the keyboard buttons. If I press up or down on the keyboard volume buttons or the keyboard mute button, I get a slider bar with 0% percent indicated. There is no change in the volume.

Which GUI/desktop environment do you use?
Also I think you need to state a bit more about your keyboard or whatever those media keys are on.

The way I setup my laptop was to modify the acpi_handler script to handle those buttons, but I don't use any fancy GUI that might get in the way, just a basic Window-manager environment (KISS):
Code:
test@ws1:~$ cat /etc/acpi/acpi_handler.sh
#!/bin/sh
# Default acpi script that takes an entry for all actions

IFS=${IFS}/
set $@

case "$1" in
  button)
    case "$2" in
      power) /sbin/init 0
        ;;
      mute ) /usr/bin/amixer sset 'Master' toggle
        ;;
      volumedown ) /usr/bin/amixer sset 'Master' '5%-'
        ;;
      volumeup ) /usr/bin/amixer sset 'Master' '5%+'
        ;;
      *) logger "ACPI action $2 is not defined"
        ;;

    logger "ACPI group $1 / action $2 is not defined"

I'm using KDE.

The relevant keys on my keyboard are f6 = mute, f7 = lower volume, and f8 = increase volume.

I don't know if it helps, but if I type lsmod, this line is part of the results:
