I just received Augio GD DI 2014 (USB->SPDIF with HDMI I2S output) and it is not working with my W4S DAC2 HDMI I2S despite the pin configuration that matches the W4S.

Wonder if any local member owns the same W4S DAC2 so I can test the HDMI I2S on a different W4S unit. I have no knowledge in electronic and do not know how to troubleshoot.

I contacted the seller (Kingwa), but he can't help me as the unit is now here and he does not have a W4S DAC 2 to test the connection.

Any suggestions would be appreciated.
