You can find drivers at this link.

Also look over the Sitara SDK 7.0 linux audio page for details on integrating new audio devices.

David, as Justin's link mentions, those are generic linux ALSA drivers. They are not made to work with only one specific processor. The problems you will encounter, however, relate to differences in the linux kernel between the version those drivers were tested on for OMAP4 (maybe 3.8 or older), and the kernel version that ships with SDK 7.0 for am335x (3.12). Look at that sitara audio page I sent you for details on how to interface an audio codec to am335x. I put lots of examples in there that will guide you step by step through the process.
