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 defaul
Hi Jakub and Marcus:
On the Mac, use the BlackHole virtual audio driver. It’s at
https://github.com/ExistentialAudio/BlackHole. You can create a virtual audio
device and point WSJT-X at it for input, output, or both. It works well and
the developer is responsive to questions and suggestions.
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.
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 set
