Essentially that is what the loopback interfaces are. So what I have done is identified the existing loopback interfaces and how they are used, I have then created a new pair ready to route the sbitx audio to a different device.
To illustrate:
Loopback 1 is used to send receive audio from the sbitx app at a fixed volume level to the digital software e.g. wsjt-x
Loopback 2 is used to capture output(mic) audio from the digital software e.g. wsjt-x and feed that back to the sbitx app for transmission
I have created a new pair of Loopback interfaces (3 & 4) to replicate this functionality with a USB connected audio device/headset but I need the source audio to have adjustable volume(gain) controls for SSB purposes.
That is the next puzzle to solve which will involve a bit of coding in the sbitx application. I will investigate this but need to better understand the coding architecture so that I can have a go at making the required updates.
At least the structural foundation is there now from a hardware perspective.
