Bash script to adjust Zoom meeting microphone and speaker volume to normal levels

zoom_set_normal_volume.sh

#!/bin/sh

LANGUAGE="en_US"

app_name="ZOOM VoiceEngine"

current_sink_num=''
sink_num_check=''
app_name_check=''

pactl list sink-inputs |while read line; do \
    sink_num_check=$(echo "$line" |sed -rn 's/^Sink Input #(.*)/\1/p')
    if [ "$sink_num_check" != "" ]; then
        current_sink_num="$sink_num_check"
    else
        app_name_check=$(echo "$line" \
            |sed -rn 's/application.name = "([^"]*)"/\1/p')
        if [ "$app_name_check" = "$app_name" ]; then
            echo "$current_sink_num" "$app_name_check"

            pactl set-sink-input-volume "$current_sink_num" 50%
        fi
    fi
done

current_source_num=''
source_num_check=''
app_name_check=''

pactl list source-outputs |while read line; do \
    source_num_check=$(echo "$line" |sed -rn 's/^Source Output #(.*)/\1/p')
    if [ "$source_num_check" != "" ]; then
        current_source_num="$source_num_check"
    else
        app_name_check=$(echo "$line" \
            |sed -rn 's/application.name = "([^"]*)"/\1/p')
        if [ "$app_name_check" = "$app_name" ]; then
            echo "$current_source_num" "$app_name_check"

            pactl set-source-output-volume "$current_source_num" 100%
        fi
    fi
done

This is because Zoom auto-adjusts when a new meeting starts, and it's annoying to change it back manually

Thanks to https://unix.stackexchange.com/questions/208784/command-line-per-application-volume-maybe-amixer-or-pactl

Thanks for the script! By the way, "Zoom VoiceEngine" keeps on resetting to 31% when I switch windows while in a meeting. If I want to use this script to fix this issue, how would I do so? Thanks for your help.
