Slice B but no DAX output to WSJT-X

Like many of you I run WSJT-X with several slices on a 6700 with no problem However, this is not the case with Slice B which although shows a DAX IQ stream being output no signals appear on the WSJT-X waterfall.  Is there something special about Slice B? I have tried everything to no avail! Grateful for any thoughts.

DAX IQ? I assume that was a typo. If you mean DAX Audio RX#. Then make sure you have selected the same DAX RX# in WSJT-x that you are selecting in the DAX pulldown on Slice B, and that you have the same DAX channel activated in the DAX Control Panel. Also check that the meter on that channel’s Indicator in the DAX Control Panel is showing audio.

Yes, sorry that was a typo!  Yes, the DAX RX's match and you see audio on the panel.  I have Slice C and D working perfectly, it's only B that fails! Even changing Slice B to another DAX Rx fails.

Diagnostic Question:

Does slice B fail when it is the only slice using WSJT-X? Or only when you have multiple slices running WSJT-X?

I had a similar problem using WSJT-X. Once I upgraded my Windows to 1709, I could not get my DAX to work on TX and the receive stream would only work on DAX-2 through DAX-8. Out of curiosity, I reverted back to 1703, and everything worked fine. I then, put my computer back to where there was no WSJT-X on the computer, upgraded to 1709 and reloaded WSJT-X and everything worked fine. I also tried removing WSJT-X on the non-working computer, re-loaded,  and still had the same problem. It seems every time Windows makes an "upgrade" things go to hell in a hand basket.

That reminds me. Check “Device Manager” and turn on “View Hidden” and examine the Audio Devices. A Windows 10 update might have corrupted your DAX drivers, leaving “hidden” or “ghosted” devices.

Look at the entries for the DAX Channels and see if any of them are doubled, missing, or don’t look like the others. If so, look at the help desk knowledge base for the article on removing ghosted audio devices.

Makes me wonder if developing an uninstall program for each program is a more daunting project than the project itself.

Thanks for the suggestions Ken and Jim,

1. Yes, Slice B fails when it is only slice.

2. Checked Device Mgr and all looks okay. Not sure what you mean by entries for DAX Channels?

3. One other important point is that despite the CAT and Radio connections being identical to all others and the "CAT Test" showing Green on the  WSJT_X settings the front digital frequency display comes up in Red. On WSJT-X with the other working Slices the digital frequency displays are in Green.CAT setup appears to be identical to others...

Screenshots of the CAT port and the WSJT-X radio configuration would help a lot.

Tim, I have shut down Slice B (tried many times before) but this time on re-installing the signals appear as they should on WSJT-X! Now only difference is that as I said before the WSJT-X front Frequency box comes up in Red despite the "Test CAT" showing Green.  HoweverI will continue to see if I can resolve this.
