WSJT-X, FLDIGI, F1500 and VAC Audio Issues

I have VAC v4.14 running with two cables set set up. In PSDR I am using for VAC1 Driver WDM-KS with Virtual Cable 1 on input and Virtual Cable 2 on output. I can find the VACs in Device Manager, however, they have DAX names with VAC in (). See attached. I tried using the DAX name but had issues regarding which pair or even if it would work. I am running Win 10 using fldigi and wsjt-x which works on on SSDR. Any Thoughts?

It appears your DAX devices have stomped on your VAC devices, you might need to remove all of the DAX and VAC devices, then reinstall them, maybe installing DAX first then VAC. I've had these issues before. Be sure to select View > Show hidden devices in Device Manager after a reboot to be sure ALL DAX and VAC devices are removed from Device Manager before reinstalling any of them. Windows often gets Virtual Sound device creation wrong, and/or mislabels them. If that doesn't correct the device names try again but reverse the order, trying VAC install first, DAX second.73, Jay - NO5J

I can remove everything except the VAC files. Not sure how to remove the VAC app since I cannot find the app in Apps & features. What am I missing?

Let me do some digging through my PC I should be able to figure out where they might be hiding.
Maybe you could drop into the #FlexRadio IRC chat channel while your waiting. I keep PowerSDR and SmartSDR installed on a multibooted Win10-32 bit partition, I'll need to reboot to be able to do the searching.
If you do join the IRC channel, I may miss you joining, due to the rebooting.
So wait around till I rejoin.73, Jay - NO5J

Don,
Windows has renamed the VAC devices. Try renaming the duplicated DAX entries to VAC Line 1 and line 2.

I got a response from Eugene - VAC author - and I was able to remove VAC - didn't read far enough in his instruction manual for "uninstallation", however, I still have all these ghost DAX Audio under Audio inputs and outputs. Is there a way to remove these ghosts?

I want to thank Jay, Andrew and Eugene (VAC). Removed SSDR and VAC. Reinstalled SSDR and VAC and removed the ghosts and now the F1500 works well with fldigi and WSJT-X.
