Volume controls

Now have volume keybinding in place. Thanks to Timo(http://www.jroller.com/page/timsu/20050215), updated script is below.
Needed to emerge xosd (already had aumix on the system), this script will work for xosd 2.2.8-14.

audio_adjust.sh:

#!/bin/sh

cd $HOME

action=$1; shift
killall -q osd_cat > /dev/null 2>&1

get_volume() {
   volume=`aumix -q | sed -ne 's/^vol \([^,]*\).*/\1/p'`
}

show_volume() {
#echo Volume:\ $1|osd_cat -o 300 -A center  -c green -s 10
osd_cat  --text Volume:\ $1 --barmode=percentage --percentage=$1 -o 300 -A center -c green -s 10
}

case "$action" in

incr)
   delta=${1:-5}
   rm -f .mutevol
   aumix -v +$delta
   get_volume
   show_volume $volume
   ;;

decr)
   delta=${1:-5}
   rm -f .mutevol
   aumix -v -$delta
   get_volume
   show_volume $volume
   ;;

mute)
   if [ -s .mutevol ]
   then
 vol=`cat .mutevol`
 rm -f .mutevol
 aumix -v $vol
 # echo "Volume: $vol" | xosd -- -
 show_volume $vol
   else
 get_volume
 [ $volume != 0 ] && echo $volume > .mutevol
 aumix -v 0
 echo "Volume: muted" | xosd -- -
   fi
   ;;
esac
