48 * VT1722 (Envy24GT) - 6 outputs, 4 inputs (only 2 used), 24-bit/96kHz
49 *
50 * system configuration ICE_EEP2_SYSCONF=0x42
51 * XIN1 49.152MHz
52 * no MPU401
53 * one stereo ADC, no S/PDIF receiver
54 * three stereo DACs (FRONT, REAR, CENTER+LFE)
55 *
56 * AC-Link configuration ICE_EEP2_ACLINK=0x80
57 * use I2S, not AC97
58 *
59 * I2S converters feature ICE_EEP2_I2S=0x30
60 * I2S codec has no volume/mute control feature (bug!)
61 * I2S codec does not support 96KHz or 192KHz (bug!)
62 * I2S codec 24bits
63 *
64 * S/PDIF configuration ICE_EEP2_SPDIF=0xc1
65 * Enable integrated S/PDIF transmitter
66 * internal S/PDIF out implemented
67 * No S/PDIF input
68 * External S/PDIF out implemented
69 *
70 *
71 * ** connected chips **
72 *
73 * WM8776
74 * 2-channel DAC used for main output and stereo ADC (with 10-channel MUX)
75 * AIN1: LINE IN, AIN2: CD/VIDEO, AIN3: AUX, AIN4: Front MIC, AIN5: Rear MIC
76 * Controlled by I2C using VT1722 I2C interface:
77 * MODE (pin16) -- GND
78 * CE (pin17) -- GND I2C mode (address=0x34)
79 * DI (pin18) -- SDA (VT1722 pin70)
80 * CL (pin19) -- SCLK (VT1722 pin71)
81 *
82 * WM8766
83 * 6-channel DAC used for rear & center/LFE outputs (only 4 channels used)
84 * Controlled by SPI using VT1722 GPIO pins:
85 * MODE (pin 1) -- GPIO19 (VT1722 pin99)
86 * ML/I2S (pin11) -- GPIO18 (VT1722 pin98)
