RF Space audio is data within the program DLL - there is no hardware
CODEC (you can't see SDR-14, SDR-IQ, etc. as a "sound card" in Windows
Device Manager)

The K3S USB audio is defined by the hardware on the specific PC (and
appears as a sound card in Windows Device Manger).

You *might* be able to find a "remote sound card driver" that will
mirror the K3S USB Audio CODEC onto a remote PC but good luck ... you
will probably have more luck using a VoIP package to transport the
audio from one sound card (the K3S) to the other (your laptop) than
installing the remote K3S sound card onto your laptop.
