I know I might sound stuck on the nodeid theory, but I have built a
working audio driver in osx & when I take the nodeid's in the pathmap of
the driver (0x14-0x0c-0x02 "hex") which is sending sound to the
headphones with the settings it see's in my codecverbs then change the
nodeid's to (0x17-0x0f-0x05) it starts sending the sound to the lineout
& so on for every other Input/output. So since the driver is working
properly its just strange that when I change the "Nodes" to (0x15-0x0d-
0x03) there seems to be no sound going to speakers, & odd Ubuntu also
has no output to Internal speakers (not familiar with alsa source yet
for comparison).

I'm just wondering if theres a way to rule out the possibility that HP
has mapped the internal speakers to non-standard nodes & their windows
driver is overriding the chips defaults which are possibly being
displayed incorrectly by the bios (I've heard of hp doing something on
those lines before). Or that there is special amplification settings for
the internal speakers, I did see inside there are 2 sets of wires going
to each speaker, (black/white) & (black/red). maybe its just because
there are 4 speakers but I would think if its stereo there'd only be one
set to each speaker for 2ch. Is it possible their powered & the codec
handles their power management?

Just sending some ideas for thought, let me know if you think I should
do something to test further.
