How to play a sound when a "XF86AudioVolume" key is pressed

Hi there,

Like the title say, I'd like to have some sound played (like a "pop") when I change the volume with the keyboard.

First thing first!
Here what I've done so far:
In Appearance settings the system sound is enable (both)
In pavucontrol system sound volume is at 100%
I've set the GTK_MODULES environment variable with canberra-gtk-module (in /etc/X11/Xsession.d)
I've set in xsettings>net>SoundThemeName => freedesktop
In /usr/share/sounds/freedesktop/ there is a audio-volume-change.ogg file among many other ogg files.

After all that, I've get few sounds when a window is maximized and minimized etc... but all I'm looking for is a sound when I change the volume... and nothing.

If I've understand things wright, The "problem" seems to come from libcanberra, Which do not implement audio-volume-change.
But is there any other way to get what I want??

PS: In Gnome, that I was using before moving to xfce, the sound was playing when I pressed XF86AudioRaiseVolume or XF86AudioLowerVolume.

Thanks

Ok I've found a way but dunno if it is a "nice way" of doing it.
I've created 2 scripts almost equivalent, one for VolumeRaise and the other for VolumeLower (code below)

#!/bin/bash
pactl set-sink-volume 0 -5%
paplay /usr/share/sounds/freedesktop/stereo/audio-volume-change.ogg

In keyboard settings, I've just added theses scripts with the correspondent key.

So now I've got the sound + notification + panel icon when I press XF86AudioRaiseVolume or XF86AudioLowerVolume

Does anybody came across a problem like this one, and how did you get it done?

EDIT:

I've made a change in the audio-volume-up.sh script. I stop it from being able to raise volume more than 180%.
Careful: volume is language dependent, it should work for English and French.

#!/bin/bash

max=180

vol=$(pacmd list-sinks | awk '/volume: f/ {gsub(/\%/,"",$5);print $5}')

if [ "$vol" -ge "$max" ]; then
	paplay /usr/share/sounds/freedesktop/stereo/audio-volume-change.ogg
else
	pactl set-sink-volume 0 +5%
	paplay /usr/share/sounds/freedesktop/stereo/audio-volume-change.ogg
fi

You are correct in that the libcanberra implementation doesn't implement the volume-change event so you won't be able to use that. And Xfce doesn't have any sort of internal mechanism to do this. The script that you've created seems to be a good implementation of this functionality. Thanks for sharing!

BTW, welcome to the forums.
