在https://bbs.deepin.org.cn/post/270279里，我知道了华为电脑不出声的原因

于是我按照上面说的，先是用sh测试了一下，运行sh是可以修复问题的，然后就想着弄一个service来开机自启

我将service放在了/etc/systemd/system/下，并写入以下内容：

[Unit]
Description=Huawei soundcard headphones monitor

[Service]
ExecStart=/usr/local/bin/huawei-soundcard-headphones-monitor.sh
Restart=always
User=root

[Install]
WantedBy=multi-user.target

然后chmod +x了，但重启/注销都无法运行，systemctl status显示：

× huawei-soundcard-headphones-monitor.service - Huawei soundcard headphones monitor
     Loaded: loaded (/etc/systemd/system/huawei-soundcard-headphones-monitor.service; enabled; preset: enabled)
