Anything from air in the lines, crappy fuel, old oil, fuel pressure, etc. Sounds fine to me as well. mine is MUCH louder.

Do you only notice the cackle when the truck is cold meaning not up to operating temp?

Do you have hard cold starting issues?

If you answer yes to the above questions you may have a injector or serveral injectors starting to stick a little or possibly alot.

The only way to properly trouble shoot sticking injectors is on a cold engine you will need to remove the valve covers and look at the oil spouts when it is running you should see an even amount of oil coming from all injectors. If one has constant flow that is a bad injector, no oil flow is a bad injector. A good injector will just spit some oil as it fires
the injector.
I could not hear too much on the video as the others.

I drove a truck with bad injectors in it and my truck has injectors that are sticking when cold.

When it is cold out there may be a valve on your truck that will create exhaust back pressure to aid in the warming up the engine. If your truck has that it causes a loss of power until warmed up to operating temp.
