If you want to have notification, then try to create a script or a 
command line adding the notify-send instruction.

Something like that:

notify-send " " -h int:value:80 -i audio-volume-high


You can get the actual volume using "amixer get Master". And you can 
extract the volume percent with something like that:

  amixer get Master | awk '$0~/%/{print $5}' | tr -d '[]%'


#!/bin/bash

# So, you can make a script getting the volume:

VOLUME=`amixer get Master | awk '$0~/%/{print $5}' | tr -d '[]%'`

# Calculate the new volume:

NEWVOLUME= `expr $VOLUME + 5`

# Increase the volume:

amixer -q set Master 5%+ unmute

# Notify the change:

notify-send " " -h int:value:$NEWVOLUME -i audio-volume-high

# and thats all!!


I hope to help you. ;)
