Yes, it took many steps but worked at the end. It was journey and I learned a lot too. I will post my exact setup when I get to my laptop.
KD9BKU - Can you post pictures of the settings you used in soundmodem like I did? Squelch and volume on the radio only affect the receive side which works for me. It’s only the transmit that I can’t get triggered.
VA7AYG - Hopefully you can post pictures like I did for me to compare.
K0TX - Is there a way to determine the firmware version of my digirig? Maybe it really isn’t v1.6.
Please see the revision printed on the back side of the PCB.
This could be the issue. Revisions 1.5 and earlier used TRS sockets. VX-6R cables is TRRS.
Here you go
K0TX, VA7AYG, KD9BKU - I FOUND THE PROBLEM. It was something stupid. First I want to apologize to you three for wasting your time and thank you for your help. The problem was I had the Digirig plugged into what turned out to be a USB 2.0 port on my laptop. After I moved it to a USB 3.0 port everything started working as it should. Transmit works on my Yaesu VX-6R and I’m sending and receiving packets.
Thank you!

I do not have, at the bottom of the Modem list, FX 25. How come? KA7ROL
I’m not 100% sure, are you running Winlink Xpress, and have you ran an update in Winlink recently?
Had the Yaesu VX-6/7 with DigiRig cables working for a few weeks; then no PTT. Have used the suggested “sound” troubleshooting and the computer, with Winlink, “hears” the radio just fine; yet nothing with the PTT side…Nether Packet or VARA-FM is working the PTT lines to the radio. Do I need a replacement cord?
It might be a cable issue. If all of your other settings are the same as before when it worked. Is your squelch at zero? Off?
Tnx for the reply: The squelch is set to “1”.

Ok , try 0 and see if that works
I can “hear” it go out but something is not pushing the PTT for the HT to transmit…
Within the Packet Winlink Session Setting under PTT Port the correct com port has been selected…have gone thru the “Dual PTT, Swap COM pins for PTT, and both blank” without the radio doing it thing to transmit.

Well, you have me puzzled. I’ll try to go through all the details on mine tomorrow and see if I can think of anything that would help.

easy thing to check:
unplug everything 
now, plug the digirig audio cable ONLY into the radio.
now, get a paperclip, and unwind it.
or a bread bag twist tie with the insulation stripped off
‘jumper’ the sleeve and neighboring ring of the digirig audio cable.
this should PTT your ht.
this should at least rule in/out the cable you’re using.

UPDATE: Thanks to Denis Grisak with the schematic of the cable and my Simpson 260 multimeter, the cable was verified good. However, going back to the radio itself the “electrical” connection was intermittent at best…screwed it two different mic/speakers, one worked, the other not, then compared all three screw side connector and there was a slight differences with the screw side. In my physical attempt to adjust the radio’s jack I rendered this portion of the radio permanently “not-available” for any further use. No cables were harmed during this troubleshooting event.
I wish to thank ALL who assisted and Denis who provided the link:
Hope this helps someone else.
