Uff, please don't recommend such stunts :) This can be solved easily in
software at zero cost.
If you're on a modern Linux, you use the pipewire audio system. Install `qpwgraph`, start
WSJT-X and just use qwpgraph to connect the output of your GNU Radio flow graph to the
input of your WSJT-X. (or vice versa, really!)
If you're using an older Linux distribution, you might still be using pulseaudio. No
problem, you just 1. create a "black hole" audio sink, then 2. form a virtual microphone
input from that:
1. |pactl load-module module-null-sink sink_name=cable_out
sink_properties=device.description=cable_out|
2. |pactl load-module module-remap-source master=cable_out.monitor source_name=cable_in
source_properties=device.description=cable_in|
You'd then use `cable_out` as device name in your GNU Radio Audio sink. That's
it.
On Windows, I'm no expert, but there's many loopback ways. there's VB-Cable, which used to
be a thing when I used WIndows the last time.
No expertise on Mac OS, but if something is Mac OS's thing, it's multimedia routing, so
that should work. In no case should you spend money on an external sound card, and live
with the quality loss of that!

Hi Jakub and group!
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!!!

Hi,
is there any simple way to redirect GNU radio Audio sink output to "wire" so
that it can be processed by some other software (e.g. WSJT-X)?
Thanks for any info
Jakub
