Thank you guys for the advices.

I'll check the shut-off valve and fill valve as Jim has mentioned.
In case that's not the problem, where are the air chamber or dump
installed? What do they do exactly?

Thanks a lot

What I'm saying is that there may actually be no damping air column pipe
(forgotten the darn terminology) as there should be. If one exists it
would probably be in a basement stud wall since the toilet is in the
basement. Could be between the floor joists above. It's just a Tee
fitting with a bit of pipe above it closed off at the top. 'S at least
possible that the top of the pipe wasn't effectively sealed, allowing
the air to leak out until there's no more air column (just a water
column), completely cancelling the effectiveness of the damping.
