Laminate with preattached underlayment that needs extra underlayment for HOA

Recently My fiancee purchased a condo and the bank put in new carpet
to help it sell. fast-forward a few months and i come home to my dog
having eaten a sizable chunk of our carpet

After looking at Lumber Liquidators, Lowes, Home Depot and Costco we
decided we liked the Vineyard Cherry from Harmonics.

The issue is our HOA requires we have a 1/4 in of felt or cork
underlayment and the wwod has a 3mm preattached foam pad. I have heard
that this can cause the links to fail.

1) Does fail mean pull apart where you just have to snap them back in?
Or fail as in broken wood?

2) I have heard that cork and "The Floor Muffler" have "robust
compression characteristics" Would this solve the issue or at least
help?

3) the preattached underlayment is 3mm and the floor muffler has a thickness of 2mm would the 2mm change much?

Any alternate suggestions are appreciated

Thank you for your time

 

Welcome to the forums

I cannot comment much on the flooring itself but can provide a bit of math - 1/4" is 1/4 of 25.4 mm which is about 6 1/3 mm, so the 5 mm you propose in #3 would not meet your HOA requirement.
