Still testing, but it seems to work. 
ใCI-Vใ็ก็ทใฎ้ ้ๆไฝ ใID-31/ID-51/IC-R6ใ - YouTube shows it working.
DIGIRIG and Ham Radio Deluxe works.
Need to test WSJT-X, VARA-fm, and Winlink.
A modified hand speaker/mic/digirig combo with PPT & PTL(push to listen) be nice to have for testing. Allowing for directed nets and monitoring signals received. Or just A/B switcher SPEAKER MIC / DIGIRIG might work.
Off topic: Does anyone monitor their DIGIRIG audio on the PC speakers?
