Cracking open Amazon's Kindle

Just above the Kindle's headphone, mini-USB and power jacks, can be found a Wolfson Microelectronics WM8971 stereo, audio codec chip, with the following markings: WM8971G 78AV7N7.

According to Wolfson documentation, "the WM8971L [which seems to have replaced the WM8971G] is a low-power, high-quality stereo codec designed for portable digital audio applications."

Wolfson's site advises against using this chip for new designs and recommends the WM8750 as an alternative.
