hi, there is a published technical service bulletin about this problem for these vehicles and the tahoes. the compressor sitting so low in the system, gets over-run by the liquid freon banging internally and actually locks up on and off during operation. this is the noise you are hearing. apparently there is a screen kit to install in the low side suction line to prevent this from happening, but GM also states the compressor needs to be replaced and the new compressors from GM at least, already have this modification done. So, i replace them when they come into my bay with the complaint you speak of, and the tensioner for the belt, likely the belt too. but it looks like you already know all about that. hope i could help.

SOURCE: Clicking noise when accelerating
It's hard to diagnose with just the small information you have stated, but it 'sounds' like it's that Exhaust Gas Recirculation Valve gasket.
In your cylinder head is a runner that brings exhaust gas up through the intake manifold.
The EGR valve is attached to the intake manifold, and the sensory part of the EGR valve sits down in the pathway of the runner.
A bad EGR valve gasket will let exhaust gasses escape, making the sound you described.

From what you are describing it sounds like it must be a valve lifter sticking. Try putting a cup of transmission oil in your crankcase, or pick up some suitable additive from your local parts store. I wish i could hear it and give you a better idea. Maybe let them listen to it at the parts store, and they can determine if it's a lifter or not. Let me know how you make out.

Misalignment of the belt, incorrect belt, worn or loose tensioner, Too tight of an adjustment (many service centers do this on purpose so when the belt breaks in it becomes properly adjusted, I do not believe in this philosophy), The belt is actually one long belt called a serpentine belt.....
