Wolfson Microelectronics WM8971 stereo, audio codec
Just above the Kindle's headphone, mini-USB, and power jacks, you'll find 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.
