26 * <-> CS4362A (addr 0011000) (surround, center/LFE, back)
28 * GPI 0 <- external power present (DX only)
30 * GPIO 0 -> enable output to speakers
31 * GPIO 1 -> route output to front panel
32 * GPIO 2 -> M0 of CS5361
33 * GPIO 3 -> M1 of CS5361
34 * GPIO 6 -> ?
35 * GPIO 7 -> ?
36 * GPIO 8 -> route input jack to line-in (0) or mic-in (1)
38 * CM9780:
40 * LINE_OUT -> input of ADC
42 * AUX_IN <- aux
43 * MIC_IN <- mic
44 * FMIC_IN <- front mic
46 * GPO 0 -> route line-in (0) or AC97 output (1) to CS5361 input
