How to run a sudo command on startup - launch daemon help

Question

I have a sound problem on my 2010 Mac mini. I found a solution that uses a sudo command in the Terminal app. But this method only works one time, so when the computer turns off and then back on, you need to start over..

Please bear with me - I'm new in this Mac universe.

From this site, I’ve found that you can use a Launch Daemon to execute it.

I can't seem to figure out a working file.

My sudo command for the sound fix is:

sudo kextunload /System/Library/Extensions/AppleHDA.kext

After that type:

sudo kextload /System/Library/Extensions/AppleHDA.kext

Remember, sudo requires an administrator password.

My idea here is to run this at startup so I don't have to type it every time.

Can someone help me write it?
