FX-4C: digirig in and out both work, but not together

This can be related to the radio’s speaker output using BTL design as discussed here:

With only the headphones cable plugged in, can you check that there is continuity between the sleeve contact on the Digirig’s end of the cable and radio’s chassis?

If there is none, then the cable will have to be modified by disconnecting the sleeve on the headphones connector.
