Re: Discuss-gnuradio Digest, Vol 260, Issue 5

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.

IMO the simplest way to "redirect" audio sink, and that's the solution I usually use, use another USB sound card for WSJT-X with an "audio splitter" and "physical crossed cable".  The audio splitter is only necessary if you want to monitor the audio.  No need for complicated settings, virtual audio cable, etc. etc...... fast and dirty!!!
