Remove the tank lid and look at the fill valve. Is it a yellow valve?
This fill valve is common on the Toto Toilets and can easliy plug with debrie.
They can be disassmbled and cleaned. however, I usually just replace the valve with Fluid Master Fill valve.
You will also want to check the water coming into the toilet by turning off the water that supplies the toilet and disconnecting the water supply line. After removing the water supply line turn on the water at the valve to make sure that the water is flowing properly. Check the supply line also to make sure it is not plugged.
Be sure and place a small container to catch the water that will come from the valve. A towell will also help from making too much of a mess.
If the Supply line and the valve are clear the problem is in the fill valve.
The G-Max system denotes the Flushiing system which is a 3" flapper that allows the water from the tank to flow into the bowl quicker.

Hi I have exactly the same problem, in fact it could have been me writing this - 3 toliets fine, main bathroom hisses. The Geberit flushing ciphen on the left (the smaller one) has been replaced and there is still a problem. If you look carefully,the water level needs to come up over the lip of an opening on the Geberit part and this causes the valve mechanism to shut off and stop the hissing. It is fine for about 40 minutes and then the hissing starts again if you don't flush it. The reason is that the water level has gone down but there is no obvious signs of where the water is going. It could be that the central flush mechanism is leaking slightly. I am going to replace this part next. If I were you I'd see if you are getting any water leakage into the pan when toilet not in use to see if the water level in the cistern is going down James T

SOURCE: cannot remove top of cistern
There are some dual flush cisterns where you have to depress one button to reveal a cavity in the second button. Put a screwdriver in that cavity to lever out the second button, then release the first button and prise that out.
Underneath the buttons is a screw which must be unscrewed to release the cistern lid.
Not sure if this will apply to you... but if not, good luck anyway.
