says that the audio CODEC is in the bottom right of this image, the Apple 66AJSTB. The site also says it ought to be similar to the Wolfson Micro WM8750, similar to the WM8975. The pinouts are the same for both chips, and so the nano 2G should theoretically work, just that I can't decipher what's going on around the chip in this image. The feeds are coming out of the left side of the chip, but I can't see where they're going. If a daring soul would open up their nano 2G (and iPod video while they're at it), that would be great for readers of the thread. Remember that there are two pairs of L/R audio feeds, and that the first pair (with lower pin number) control the headphone jack, and as such have their volumes digitally controlled. The second pair, which should sit at the very bottom left of the 66AJSTB we see here (if it is indeed the same as the Wolfson chips), would be where you want to grab the signal.
