通过 systemd 运行 aplay

按照这个帖子，我似乎可以通过运行来解决声音播放问题aplay -f cd /dev/zero。我已将命令放入脚本中~/Scripts/openAudio。我希望脚本从登录运行。我已在创建此文件/etc/systemd/system/openAudio.service：

[Unit]
Description=open the audio

[Service]
Type=simple
ExecStart=/home/gareth/Scripts/openAudio

[Install]
WantedBy=multi-user.target

然后我这样做了：

sudo systemctl daemon-reload
sudo systemctl enable openAudio
sudo service openAudio start

该命令systemctl status openAudio给出如下结果且无需运行 aplay：

× openAudio.service - open the audio
     Loaded: loaded (/etc/systemd/system/openAudio.service; enabled; preset: enabled)

关于如何让 aplay 命令从登录时自动运行，有什么建议吗？

编辑：我发现了一个类似的问题这里，但遗憾的是没有答案。
