How can I run a sudo command automatically on startup? I need to run sudo alsactl restore to mute my microphone from playing In my own headphones on every reboot. Surely I can delegate that to the system somehow?
If you run a systemd distro (which is most distro, arch, debian, fedora, and most of their derivatives), you can create a service file, which will autostart as root on startup.
The service file
/etc/systemd/system/<your service>.serviceshould like[Unit] Description=some description [Service] ExecStart=alsactrl restore [Install] WantedBy=multi-user.targetthen
systemctl enable <your service>.service --nowyou can check its status via
systemctl status <your service>.serviceyou will need to change
<your service>to your desired service name.For details, read: https://linuxhandbook.com/create-systemd-services/
This one seemed perfect but nothing lasts after the reboot for whatever reason. If i manually re-enable the service its all good so I suspect theres no issue with the below - I added the after=multi-user.target after the first time it didn’t hold after reboot.
[Unit] Description=Runs alsactl restore to fix microphone loop into headphones After=multi-user.target [Service] ExecStart=alsactl restore [Install] WantedBy=multi-user.targetWhen I run a status check it shows it deactivates as soon as it runs

after=...solve the problem or cause the problem? Sorry, I cannot parse what you were trying to say.It seems to have no effect either way. Originally I attempted without, then when it didn’t hold after a reboot and some further reading I added the After= line in attempt to ensure the service isn’t trying to initiate before it should be possible.
I can manually enable the service with or without the After= line with the same results of it actually working. Just doesn’t hold after a reboot.
Running something at start-up can be done multiple ways:
Try paveaucontrol, it has an option to lock settings plus it’s a neat app to call when you need to customise settings. You could also add user to the group that has access to mic.
You got some good answers already, here is one more option: Create a *.desktop file to run sudo alsactrl, and copy the *.desktop file ~/.config/autostart (Might need to configure sudo to run alsactrl w/o password.)
IMHO the cleanest option is SystemD.
