Hello! I have WM8805 in software + AK4393. But I can't get it to output Unlock status to GPO4 pin, it always "0", please check up my code:
It configured as master with 24.576 Xtal , RX3 input and i2s output 24bit, several GPO pins directly connected to ground on the board, that's why i setup wm8805 to output other GPO pins in "0" . I2S flow from wm8805 output properly.
 writeto8805(0x03,0x33);     //fraktal k0 
 writeto8805(0x04,0x33);     //k1
 writeto8805(0x05,0x2B);     //k2
 writeto8805(0x06,0b10111); //Prescale = 2

 writeto8805(0x08,0b01011);  //RX3 input 
 writeto8805(0x17,0xff);             // gpo0,1 to 0 level
 writeto8805(0x18,0xff);             // gpo2,3 to 0 level
 writeto8805(0x19,0b11110111);             // gpo4 to unlock
 writeto8805(0x1A,0xff);             // gpo5,6 to 0 level 

writeto8805(0x1C,0b01001010);     // Master mode / 24bits / i2s
writeto8805(0x1D,0b00100000);     // no 192 / GPO outputs

writeto8805(0x1E,0b000100);       // Start clock
