I cannot speak for P170HM as I do not have one, but on P150HM there are
two speakers between the screen and the keyboard and something supposed
to act as a subwoofer on the bottom side of the laptop. On Windows 7 you
need THX TruStudio PRO to make it work. No center speaker that I know of.
There are service manuals with schematics for these laptops floating
around the internet. ALC892 connections are described on page 86 for
P150HM and page 91 for P170HM. You should be able to understand far more
than I.
