Intel HDA is a very flexible design - there's so much variation from one

machine to the next, you really need to find someone with the same

laptop who can verify that sound works.
It might be helpful to search the ALSA bug tracker for that laptop and

codec.
Ideally you would have the opportunity to test a recent live CD distro

on it before buying.
