Need sound at restart

I'm trying to make the system launch sudo alsa force-reload, which seems to do the trick for me, but I don't know how.

I've had trouble with the autostart app, which seemingly ignores my shell script for running "pkexec alsa force-reload," and I'm having trouble with editing the sudoers file despite instructions on the web.

I'm running Ubuntu 18.04 "Bionic Beaver."
