May be this noice is from compressor but you still think it is from alternator?

Start with simple things first. A high-pitched oscillating or chirpy sound can come from a dry belt. Try spraying some PTFE spray on the belt that runs round the A/C and power steering on the left hand side of the engine. If this shuts it up then its just the belt and nothing really to worry about. You can either replace it, get some belt-bandage (which is a spray for noisy belts) or just keep spraying the PTFE on it every couple of months.

i just posted about similar thing to this, if i spray the belt the noise stops but only for a couple of days, do you think that just replacing the belt should cure this there seems to be no nicks or anything in it so how do you tell if its worn thanks

In the past, when you had a screeching noise from the drive belt, it was either not tensioned properly, or the belt had seen better days. I used to remove the belt. and inspect both the sides, and inside, where you would find cracking, when you flexed it. Which was a sure sign that the belt was gone. It was then changed, and also rechecked (for proper tension), after the first 500 miles, as new belts do stretch to begin with. Do you find that the noise is more, when it is, or has been raining ?.

Don't be tight, get a new belt fitted if you haven't already. It's noisier with the aircon on because you are putting a load onto the belt.
