It would seem from what you say that the SkySong is in one clock domain and the rest of the DSD192 is in another. Both need to be in the same clock domain. Have a look at the TAS1020 and look for a connection to pin 3 and if it is present look for where it comes from.

As things stand you have pins 35, 37 and 38 connected. Try connecting MCLK from the SkySong board to pin 39.

Might a bit tight on bandwidth. Compare the MCLK signal from the TAS1020B with that from the SkySong. Also, with LRCLK as the trigger, have a look at the position of the data from TAS1020B and the SkySong.

If CSYNC is on channel one and CDAT0 is on channel two, then you should set channel one as trigger.
