Solved Sound Routing in Windows 11

It is a special problem that I want to solve.

I am a ham radio guy (F4JKH). I do digital transmissions with my radios connected to the computer via USB for Audio in/out and control.
I have a software (WSJT-X v2.6.1) that decodes and codes digital sound via USB sound codecs as input and output devices for sound. WSJT-X has options to select the soundcard inputs and outputs by pull down menu. This works pretty fine and I am happy about it.

Sometimes, I would like to connect to the sound output of my Firefox browser (v 123.0). I would like to decode that digital sound coming from a Website that runs a Webservice of a SDR (Software Defined Radio). This sound output is routed from Firefox directly to the Realtek soundcard analogue output. However, I rather want this sound to stay in the computer and have it routed to the WSJT-X software.

Means... I would like to tell Firefox to use a different sound output and I would like to tell WSJT-X to pick up exactly that sound.

Question:
What do I need to do to solve this internal sound routing problem? A hardware solution - connect the output to the input - would work, I know that, but it would disable my Loudspeaker output or force me to do hardware connection changes all the time which I do not want to do.

Thanks for any help - 73!

You could use VoiceMeeter Audio Interface or their virtual cable solutions. I've used their apps and it's great for routing different audio sources to different outputs (both hardware and software routes are supported, virtual ports) , allthough a bit complex to wrap your head around as a beginner.

The tools are free to use (donationware) but start to nag after a week or two that you should grab a license.

Thank you very much, this was exactly the solution I was looking for.
It is working very well.

Case closed!

I am glad to hear this! Enjoy!

You can even route/share your audio over local network, if you need to. This is very useful if you have a dedicated computer for audio sources and want to edit and record stuff on another computer. Or maybe want to monitor audio in your whole house. Use your imagination here

Very powerful tools.
