You cannot avoid Windows. The radio is 90% Windows software and 10%
hardware due to the thick client architecture. And the audio latency via
VAC is actually *LESS* than it is using what amounts to a custom soundcard
in the hardware unit. The audio path using the built-in audio hardware is
more torturous than VAC. See:

https://apache-labs.com/community/viewtopic.php?f=12&t=2612

Therefore there is absolutely NO reason to avoid VAC related audio
solutions.

I effectively do this exact thing, although it's only about 100 feet of CAT
5 to my basement. Take a look at my qrz.com page, click the links and read
the description of my station. And I handle all audio using VAC.

This will be a total waste of your time and will create far more latency
and complexity than simply using VAC and Voicemeeter Potato.

You can use Banana, but I'd recommend Potato: "VMP" :-)
