I've been trying all morning to find the name of the audio chip in my latest-rev MacBook. The drivers/software under Windows XP absolutely suck. The software feels the need to tell me when I've plugged in my headphones! And sometimes it gets mixed up and thinks headphones are plugged in, and it won't play sound through the speakers until I plug in a set of headphones and unplug them. So, does anyone know where I can get just the drivers for the RealTek sound system in my MacBook? I've searched on the restore DVD that I use to install Boot Camp in XP, but it only has the bundled software with the driver.
