Laminate floor with two layers of padding

Hi, we bought a mid-century house a little while ago and are

In the dining room, we're going with a floating floor, 12mm stuff from LL. This type of floor already has a padding glued to the backs of each board. The concern is that it'll sound hollow. LL says we can add a second layer of padding to help reduce noise. They don't say if it's within the specs for that particular floor, so, there's that. Plus, now that I've read a bit about floors, more padding can equal more movement, which means more creaking from the ends of the boards. So, do I get a nice second pad to add to the one that it comes with? Also, this is going over an old linoleum floor, which is pretty solid and not squeaky, so I'm not worried about subfloor movement.

It is the nature of laminate to sound hollow. Mechanically fastened floors sound solid because everything is either nailed or glued down. Floating floors will never achieve this level of solid and is a drawback of a click lock floor (laminate or engineered). Do not add an additional layer, it will not solve anything and void your warranty and potentially lead to weakened joints and floor failure.

Want a solid floor use nailed down engineered floor or real solid wood.
Laminate will do noting to increase the value of the home, will delaminate if it gets wet, looks like plastic, and sound hollow.
