Please help!!

When I test the modules, I use a S/PDIF source, which would not work if the IP_S header was shorted. I am trying to figure out what might be the cause, so a god picture of the top and bottom of the board might help.

You can cut the trace between the last pad (under the letter "S" in IP_S) and the pull-up resistor (R1). You can then solder the switch wire to the resistor pad, rather than to the S terminal.

Sorry Brian, the mod didn't work, after cut the trace, the IP pad still found short with the resistor wire, anything I can do with it?
