I have a HP NC4000 laptop that I am trying to get working with windows 7. Everything is working apart from the audio, where I can't find a functional driver. HP only supports this model up to XP and none of the XP drivers work, even in compatibility mode. There is also some confusion over the exact audio chipset this uses. Some say it uses an ALI audio device, whereas HP XP drivers are for an ADI (analog Devices Inc.) Soundmax onboard sound device.
I just opened up the laptop and am trying to identify the exact audio chip to make life easier. I have taken some pictures of the motherboard where the sound ports are. Any idea where I should be looking? Please see these pictures I have taken:
