Hi!
Just ordered a DAC from you and can't wait to try it with pimusicbox.
On the PCB, there is an unpopulated header area labelled "i2s" and I guess it reflect the lines coming from the P5 header of the Raspberry Pi. As I might be using the I2S header of the DAC board for other purposes, could you please supply the pinout of the unpopulated i2s header?
Thanks!

HiFiBerry team Hi Hans,
these pins can't be used for other purposes. They transport the sound data between the Raspberry Pi CPU and the DAC.
Best regards

Hanns Kucer Ok, I just received my board and turns out it (R2.2) does not have the I2S label so never mind.
Thanks. -
Hanns Kucer Tried the board out today with pimusicbox and after having forced "i2s" output in config, it works well. Good job!
Since sck of pcm5102 seems unconnected, I take it, you are relying on its internal PLL to recreate master clock from the bit clock. If so, why is this, RPi cant supply it?
Took out the scope and could see 16 bits at 44,1kHz judging from lrck and bck. I suppose there's no upsampling (pointless, I know) and so to get higher res (eg 24bits@192khz), I need to play higher res audio file - yes? -
HiFiBerry team Hi Hans,
yes the PLL is using SCL as clock source. Upsampling depends on the application. Some applications do upsample the signal. E.g. in Volumio you can configure upsampling.
