Microphone and audio connectors issue

I just tried connect standard 3.5mm headphones with mic to Microphone and
audio connectors sockets of my Dell Vostro 1520 laptop and find that both
Mic and audio connectors sockets are extremelly tight, so I need apply very
strong effort in order fully insert jacks into sockets..
It's not normal, so am worried about laptop motherboard, I think Mic and
audio connectors sockets are soldered onto motherboard, so force plugs into
the socket with extra pressure can damage something.
What do you think? Is it safe?

Thanks.

I see two black 3.5mm jacks in the lower left of this picture. Each
has a total of eight solder points, of which three points might be
for mechanical support.

I can't find any documentation, to suggest the jacks aren't ordinary ones.
Looking at a 3.5mm plug I have on hand here, it looks like there
might be enough depth in those jacks, to accept it.

Did you visually inspect the hole in the jack, for foreign material ?

The contacts use spring force, to ensure contact, which provides
some resistance on insertion.

I tried connect this headsets on another notebook, and connector plug fits
into the socket normally. So the issue is jack sockets.
I inspected holes and seems one of them(audio) has a a little smaller gap
between spring and contact.

Thanks

There are some jacks, which are dual mode, and have TOSLINK inside the
same jack. If you look in the barrel of the jack, you see red light coming
from a red LED, if that is the case.

They look pretty ordinary to me. I wasn't able to find any documentation
to explain how they're different.

On a spare parts web page, they show a picture of the jack assembly.
Apparently, those two audio jacks, are on their own printed circuit
board. Now, to connect the audio signals, would take five wires. Yet,
the white connector on the end of this assembly, has about eleven
connections. So there are six connections not accounted for.
Perhaps the audio chip is part of the assembly ? I'm not sure what
that means. It means the module can be removed if it is damaged,
but they might not be using screws and nuts to hold it in place.

With these pictures, it is so hard to reach any conclusion.

Its regular ordinary audio sockets. Seems assembling of these sockets wasn't
accurate enough, and spring inside is too hard. I just will not use audio
sockets as I 'm not sure i can safely force plug into sockets.
