Huy - May 30, 2023

I recently purchase the PO100 Pro as my I2S interface to my Topping D90. I tried matching both the I2S interface setting for both the D90 [STD – LRCLK – DSD Flag 15] and the PO100 Pro [Mode 2]. The manual has both of the pin out as matching but I am not getting any sound. Coaxial and Toslink is working fine. I install/reinstall drivers. I also updated the SMSL USB firmware for the device as well. Still no luck. I tried several other configurations of the D90 and PO100. Any suggestions? Thanks.
