Under Linux, a simple approach is to use a loopback (essentially establish a Virtual Audio Cable). The loopback is established by
sudo modprobe snd_aloop enable=1,1 index=10,11 The WJST-X audio input is then plughw:CARD=Loopback_1,DEV=1 and the GNU Radio audio sink device can be left as default. However, if the intent is to use WSJT-X, there is some extra complexity. WSJT-X assumes it is communicating with a transceiver (a rig) and will look to check that the rig is configured consistently with what WSJT-X expects. So you need another program that emulates a chosen type of transceiver (eg a Kenwood TS-2000) and responds to those WSJT-X checks. Switching between Tx and Rx requires some similar complexity.
