Shouldn't each connection have its own ground line ?
But on the COD board there is only one ground pad........
I connected all I2S grounds at the same connection
okay, I'm assuming that MCK = SCK (master/system clock respectively).
even hooking these together I'm still not getting the lit lock led.
I'm using an older CD transport that may not do more than 44khz but I'm confident this isn't the problem since the same transport works well and without issues on other dacs.
Voltage is ok and checks out. 7.5VDC to the 4:1 MUX and 5.5VDC to the COD (DAC) and I'm only using s/pdif coax from the transport since I don't have anything else. Furthermore the switch on the MUX is switched "closed" for enabling input '1'.
Is there a recommended procedure in troubleshooting the MUX?

is there a specific forum for this combination? All I had found was this thread and another for the MUX, but nothing caught my attention for a "support-specific" thread so I guess I high-jacked this one.
Photos shortly following.

Quick update:
I'm not able to upload multiple photos here.
In the meantime I have assembled the s/pdif module and have tried an alternative s/pdif source without success.
The mux its on top the dac module. Let me know of you need to see something specific that isn't visable in the photo.
Thanks

An externally hosted image should be here but it was not working when we last tested it.
