无法在 shell 脚本中使用 aplay 播放声音

Question

这是我希望运行的 shell 脚本。我希望收到电池通知。

但是，当我在全屏模式下观看视频时，它不会给我通知。所以，我添加了 aplay 来播放通知声音。尽管如此，还是不行。

您甚至可以向我推荐更好的电池通知程序。

我正在使用 Linux Mint Mate 20.3 .

文件内容如下：

#!/bin/bash
#please install acpi before using this ==> sudo apt install acpi
while true; do
    export DISPLAY=:0.0
    battery_level=$(acpi -b | grep -P -o '[0-9]+(?=%)')
    ac_adapter=$(acpi -a | cut -d' ' -f3 | cut -d- -f1)

    if on_ac_power; then                   #check if AC is plugged in
        if [ $battery_level -ge 95 ]; then #check if the battery level is over 90%
            notify-send -u critical "Please, kindly unplug your AC adapter" "Battery level: ${battery_level}%" -i battery-full-charged
            # sleep 300
        elif [ $battery_level -le 20 ]; then
            notify-send -u critical "Thank you!!!" "You did an excellent job, Keep it up." -i battery-caution-charging
            sleep 300 #sleep as charging upto 20 take 15 min max
            # break
        fi
        #if [ $ac_adapter -eq "off" ]; then
        #    notify-send -u critical "AC Adapter" "The AC Adapter is off."
    #fi

    fi

    if [ "$ac_adapter" == "off" ]; then
        if [ $battery_level -le 20 ]; then #check if the battery level is over 90%
            notify-send -u critical "Please, kindly plug-in your AC adapter" "Battery level: ${battery_level}%" -i battery-caution
            # To get the sound notification
            aplay sounds/mixkit-wrong-answer-fail-notification-946.wav
            # break
            # sleep 180
        elif [ $battery_level -le 30 ]; then
            notify-send -u critical "Charge it man its ${battery_level}%" -i battery-caution

            # To get the sound notification
            aplay sounds/mixkit-bell-notification-933.wav
            # break
            sleep 200
        elif [ $battery_level == 40 ]; then
            notify-send -u critical "Its ${battery_level}%" -i face-angel
            # To get the sound notification
            aplay sounds/mixkit-bell-notification-933.wav

            # break
            sleep 180
        elif [ $battery_level -ge 95 ]; then
            notify-send -u critical "Thank you!!!" "You did an excellent job,Now remove the charger." -i face-angel
            # To get the sound notification
            aplay sounds/mixkit-melodical-flute-music-notification-2310.wav
            sleep 90 # sleep as charging is above 95
        fi
  
  fi
    sleep 5 #wait for 300 seconds before checking again

done

我发现声音文件夹不在正确的位置。所以我将声音文件夹复制到 ~/music/BatteryNotifySounds 并反映了上面脚本中的更改并完成了。
