Как установить верхний предел громкости в PulseAudio?

#!/bin/bash

# Setting the Variables for execution
LOGDIR=$HOME
CURRENTTIME=$(date +"%Y%m%d%s%H%M%S")
LOGFILE=${LOGDIR}/chgpermission_${CURRENTTIME}.log
MASTERFILE=$1
INDEX=0

# Checking the number of Parameters passed
if [ "$#" -ne 1 ]; then
    echo "Master file name is mandatory parameter" > ${LOGFILE}
    exit 1
fi

# Loading the Master file into an Array 
echo "Loading the Master file ${MASTERFILE} into an array" >> ${LOGFILE}
while read line
do
#echo $line  
MASTERARRAY[$INDEX]=$HOME/$line 
INDEX=$(expr $INDEX + 1) 
done < ${MASTERFILE}

echo "Number of parameters in an master array ${MASTERARRAY[@]}" >> ${LOGFILE}

# Changing the permission of the file 
echo "Changing the permission of the file in master file ${MASTERFILE}" >> ${LOGFILE} 
index=0
for index in "${MASTERARRAY[@]}"
do
    if [ -f "$index" ] 
    then
       echo "$index file exist"
       echo  "$index file exist" >> ${LOGFILE}
       chmod 755 "$index" 
       chown workstation "$index"
       chgrp workstation "$index"

Вы можете сделать это с помощью следующего кода bash 

#!/bin/bash
x=$(pactl list sinks | grep '^[[:space:]]Volume:' | head -n $(( $SINK + 1 )) | tail -n 1 | sed -e 's,.* \([0-9][0-9]*\)%.*,\1,' )
if [[ $x -le 200 ]]
then
    pactl set-sink-volume 0 +5% 
fi

В этом томе хранится переменная x
