3 * Apple Onboard Audio driver for Onyx codec
7 * This is a driver for the pcm3052 codec chip (codenamed Onyx)
10 * The Onyx codec has the following connections (listed by the bit
12 * 0: analog output
17 * the digital output connected but not the analog, I have handled
24 * But snd-aoa assumes that there's at most one card, so
