It is not like when you try to shift a manual stick without the clutch. But a lot lighter than that varying in amplitude (louder and lower) and probably is only there when the engine is cold (Because I don't seem to observe it after I have driven a few miles).

How I confirmed? On neutral gear, I paddled the gas the sound goes louder but when I press the clutch and then paddle there is no sound.

So does it call for a gear box repair?

PS: and yes I could observe this back when I used to turn the A/C on, back then the sound was very low and when I would press the clutch it would disappear.

If this is a gear box repair thing can I delay it? or it would cause nine stitches later on?

If the sound goes away when the clutch is depressed then the sound is coming from the rotating internals of the gearbox, depressing the clutch will allow them to come to a stop (bear in mind that it's a constant-mesh box, so if the clutch is up then the internals spin even in neutral when the car is stationary)

The best diagnosis is to drain the gearbox oil, it should be clear and a light caramel colour, if there is evidence of metal filings then the box is worn or worse.

This is also a good opportunity to refresh the oil and make sure that the oil level is correct, which can both have a positive effect on gearbox performance, life and noise.

It looks as though you're concerned about cost, and oil change is inexpensive compared to the cost of gearbox repair, especially if you can do it yourself.
