(continuation of last comment) You must then map the XF86Audio* keys to commands to adjust your audio properties. How you do this is dependent on you window manager.
For xfce, in ~/.config/xfce4/shortcuts/Custom.xml, I have the following: <shortcut command="/usr/bin/amixer -q set PCM 2- unmute" keys="XF86AudioLowerVolume"/> <shortcut command="/usr/bin/amixer -q set PCM 2+ unmute" keys="XF86AudioRaiseVolume"/> <shortcut command="/usr/bin/amixer -q set PCM toggle" keys="XF86AudioMute"/> -- Panasonic R4: hotkeys and s3 don't work in edgy https://launchpad.net/bugs/62620 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
