IIS pin configuration with Gustard A26 DAC

[Dimitri_2449]

Hello,

I have just received my Matrix Audio X-SPDIF 3 and want to know which pinout configuration to use to feed my Gustard A26 DAC.

I've tried all four possible options and only mode B and D are correct as A and C are switching the left channel to right and right channel to left.

Since both B and D are working, which one to chose. I thought only one mode could work out of the 4 and not 2.

Also, what should I set the MCLK mode switch to?

Thanks!
