It seems your DAC doesn't accept mclk signal.

He connected the MCLK signal to GND.

Can you find this line in the boot.ini to double check? It is not visible on your screen capture.

setenv bootargs "console=ttyS0,115200n8 console=tty0 root=/dev/mmcblk0p1 rootwait rw no_console_suspend vdaccfg=0xa000 logo=osd1,loaded,0x7900000,720p,full dmfc=3 cvbsmode=576cvbs hdmimode=${m} m_bpp=${m_bpp} vout=${vout_mode} ${disableuhs} ${hdmi_hpd} ${hdmi_cec} ${enabledac}"

Anyway,
Once [setenv disableuhs "disableuhs"] line is uncommented, there should be another ODROID DAC item on the MPD Configuration menu.
So your OS image could be corrupted.

I tried to make a I2S cable for my Audio-gd NFB1 (ES9018). I'd asked Kingwa from Audio-gd about connection from the I2S output to the RJ45 input and he said I was right (see below) ...
I enable DAC in boot.ini (even if my DAC is ES9018 and not PCM5102) but unfortunately, I can't have sound fron my C1+...

Connections for the RJ45 pin map is (ES9018, so MLCK is going to GND):
Pin 1 : SDATA
Pin 3 : LRCK
Pin 5 : SCLK
Pin 2,4,6,7,8 : GND

And the map for Odroid 7 pins is :
Pin 1 : GND
Pin 2 : I2S data in (reserved)
Pin 3 : 5V
Pin 4 : I2S MCLK (Master Clock)
Pin 5 : I2S LRCLK (LR Clock)
Pin 6 : I2S SCLK (Bit Clock)
Pin 7 : I2S Data Out (for DAC)

So my cable's map, according to Kingwa, is (RJ45>Odroid 7 pin) :
[RJ45]Pin 1 (SDATA) > [odroid]Pin 7 (I2S Data Out)
[RJ45]Pin 3 (LRCK) > [odroid]Pin 5 (LRCLK)
[RJ45]Pin 5 (SCLK) > [odroid]Pin 6 (SCLK)
[RJ45]Pin 2,4,6,7,8 (GND) > [odroid]Pin 1 (GND)

And no sound :/

I tried to do the same for my old RPI2 without more success but probably because of the DAC interfaces in /boot/config.txt that need I2C bus response (see HERE)
But this time, I don't understand why it goes for Teradak Sabre ES9023 or Audiophonics Sabre ES9023 and not for the NFB1
