OK, so I am sitting here having a cup of coffee and chilling and notice a weird chirping or whining noise.  I have heard it before but never gave it a second thought.  So, I go looking for it.  It only happens for a half a second and not with any consistency, so I am chasing something that isn't going to be easy to find, so I think.  I realize that it is coming from my kegerator.  I look and it happens right as I open the door.  It is the gas line into the keg or the keg itself.  I think, crap, I have a leak.  I have had the keg for a few years now and have not changed any of the Orings, so I am thinking that must be it.  I get a bottle of Starsan and spray the posts, the lid and the prv.  No bubbles.  Weird.  The tank has been hooked up for at least two weeks and the gauge still shows above half full, where it was when I hooked it up minus maybe a little.  So, is it just the beer absorbing some of the CO2?  Anybody have any input on this one?  If it was a leak, even a small one, I would see a drop in the amount in the tank so I am kinda at a loss here.  Any input is appreciated.

Chirping or whining don't ring a bell for me.

As for the high-pressure gauge, it will read the same (any variation will be due to temperature) until all of the liquid CO2 has been exhausted and you're, literally, running on fumes.

Chirping or whining sounds like a bad fan to me, but it could be something else. If one of the CO2 connections is a problem you should be able to home in on it by systematically disconnecting pieces of your tubing and checking for the sound.

I get that sometimes from my 44 year old beer fridge. Usually it's caused by an ice dam that the fan is hitting.  Unplugging it overnight melts the ice and it's fine again.
