vx-6r yaesu digital modes inquiry

[Samudra Haque]

Hi, I got my trusty Yaesu VX-6R hooked up to an external antenna from my 
QTH in SW DC. I can reach W3NAN (GARC repeater) and W4HFH (ARC 
repeater)  from here for the first time reliably. Possibly NVFMA 
repeater network as well (haven't tried any contacts).

Got the programming cable as well!

I would like to explore any digital modes using this H/T and my local 
Windows 10 laptop. Does anyone have a suggestion on the type of 
cables/software I could try to use - or does anyone have a computer 
sound interface they are willing to trade that matches this yaesu 4-pin 
TRRS plug interface?
