Actually you said it does make the sound while driving in a previous post. The transmission has whats called a Front pump to move fluid through the trans. It is driven by the torque converter which is connected to the flexplate, fflexplate is connected to the engine crankshaft. So front pump is basically engine driven and is pumping fluid whenever the engine is turning, including startup.

But forget all that for a minute. After listening to the video again (computer instead of phone this time), I'd have a closer look at the power steering system. The noise at startup sounds very similar to the sounds when you had the steering at full lock. Check the fluid level, they usually get noisy when they are low, and it sounds like the pump is sucking dry at startup. Also make sure none of the lines are kinked especially the return line, the return is the flexible one that doesn't have crimped on metal ends. Power steering fluid shouldn't have a color and is fairly clear. If its turned brown or is no longer clear that would indicate a problem in the system also.

Edit: This post was in reference to the 1st video. I totally missed the fact a 2nd video was posted. The quality is not very good and its always hard to judge when not in person. I don't know what to make of the 2nd video.

The transmission, if this were the cause, would the noise be constant, or only at shifts/certain points?

I just checked the power steering fluid, container is topped off to the fill-level line, but is a very dark color.
I touched the lid with a rag and turned to a slightly red-ish color?
Almost crimson.
I'm leaning towards rust dilution colored, but I can't be sure.

I would've touched the main container, but it's like an obstacle course to get in there.

Steering though, feels.. fine?

To be brief, the second video is just hearing the same sound @ the 2k rpm point.

Winner winner, chicken dinner!

Dad took it to a shop that we've been with for awhile.
Had a guy look at it, and he first suspected a cam shaft (This is the rod knock, right?), but after closer inspection saw the torque converter was very loose. Tightened it up, and it worked swell.
Drove out with a $50 bill, which isn't bad at all!

Though now, I'm wondering if we could have done it as fast as he did.. or double the time..

Haven't been home yet, so I can't test if the steering sound is still there, or the 2k rpm issue.

Thanks for all the help guys!

EDIT: Took it out for a spin, everything is all well again!
Steering sound is gone, 2k rpm noise is gone, and startup sound is gone.
Starting to like this Kia!
