This is mine (used for adjusting the mono output speaker on a desktop)

Usage: volume.sh [up|down|mute]

#!/bin/bash

VOLSTEP=2
MASTER='Master Mono'
OFF_STATUS="[off]"
STATUS=`eval amixer get \'${MASTER}\',0| grep 'Mono:' | cut -d' ' -f7`

if [ "${1}" = "up" ]; then
        if [ "${STATUS}" = "${OFF_STATUS}" ]; then
                eval amixer sset \'${MASTER}\',0 unmute
                eval amixer set \'${MASTER}\',0 0
        fi
        eval amixer set \'${MASTER}\',0 ${VOLSTEP}+
fi
if [ "${1}" = "down" ]; then
        eval amixer set \'${MASTER}\',0 ${VOLSTEP}-
fi
if [ "${1}" = "mute" ]; then
        if [ "${STATUS}" != "${OFF_STATUS}" ]; then
                eval amixer sset \'${MASTER}\',0 mute
        else
                eval amixer sset \'${MASTER}\',0 unmute
        fi;
fi
