Can someone help me to connect this PCM5102 to Vim1? A pins little different from topicstarter’s one… 
SCK --> PIN29 / I2S_SCK
DIN --> PIN31 / I2S_SDO
LCK --> PIN32 / I2S_LCK
GND --> PIN28 / GND
VIN --> PIN27 / VCC3.3V
Enjoy!

Thanks Gouwa! At first it didn’t worked but I’ve also connected BCK to pin 30.

I think need to connect SCK to 30pin and BCK to 29pin .
can someone help me. I have a vim 2g/8g with libreelec 8.2.3.1 in mmc, but there is no chance to get the i2s signal. The connection is BCK <> GPIOH_7 (pin 29), DATA <> GPIOAO_9 (pin 31),LRCK <> GPIOH_8 (pin 32), gnd is pin 28. With the vim2 it works, but here no chance.
What can i do ? Thanks
So if we have a i2C dac we can hook it up on the vim2 and it will work?
YES! this one proper connection for i2s DAC

To make this DAC work in ubuntu/linux, did you have to modify any config file or it just works by just connecting the board and it appears in sound output options?
@Yasir_Javed after connecting the DAC, you might need to specify the audio sink to I2S, but I think it should work automatically

Hello,
Just to point out that in my case I had to invert bck and sck (compared to @Gouwa message) to make it work in my pcm5102
so I connected
SCK → PIN30
BCK → PIN29
DIN → PIN31 / I2S_SDO
LCK → PIN32 / I2S_LCK
GND → PIN28 / GND
VIN → PIN27 / VCC3.3V
Putting SCK on a ground pin also works (it will use internal clock)
