based on that pictures you need more...
SDA1/SCL lines for control the Audio Chip, they obviously using a I2C mode.
I'm not see reason to use ID_SD/ID_SC pins.
You need use a GPIO from VIM for controll GPIO6/DMUTE signals.
And power ,+5V (probably), +3.3V and at least two GND pins.
let say recommendations:
RASP <----> VIM
SDA1 <----> I2C_SDA_A
SCL1 <----> I2C_SCL_A
GPIO6 <----> GPIOH_5
I2S as was written
