No RF out with WSJT-X and SmartSDR 1.5/DXLAB

Flex 6300, SSDR v1.5.1.70.  Using DXLAB Commander v11.9.3 as radio in WSJT-X.    I am new to Flex.  I had WSJT-X working FB and made QSOs.  When I returned to WSJT-X I was unable to make any contacts.  I did NOT click on my saved profile.  This is probably the root of the problem.  So, trying to get JT back I changed something and when I did I received the profile.  Mistake because the error is now in the profile. 

I can copy FB, watching this mornings DX scroll by.  I cannot get the rig to transmit.  I realize that this may be a single click somewhere but I have been unable to find the key.  Trying to transmit/receive using DAX Channel 1.  DAX Control Panel shows Slice 1 TX, streaming when on receive.  TX Gain shows nothing when attempting to transmit.  IQ Stream shows 1 is streaming.  DAX button on the right side of screen is lit.  JT is trying to transmit, the waterfall (JT) stops but the rig does not transmit.

Bottomline is that I don't know in which of the three programs my setting is incorrect.  Advice on steps to solve would be appreciated.  Thanks.

Not sure if you're using CAT or VOX in WSJT's settings to TX, but I've had a similar issues that I face almost daily....

Here's what I do to resolve the issue. I'm using VOX to key the rig. I'll load up everything as normal, but when I hit the TUNE button in WSJT-X, the program sends audio, which I can verify by pulling up DAX's control panel, but SSDR doesn't key. Leave TUNE on, so that audio is being sent, and click the MOX button in SSDR. Boom, there's audio flowing for me. I'll click and unclick MOX a few times, and click TUNE in WSJT-X to stop sending a carrier. Then, with no manual MOX intervention, I'll click TUNE again and now VOX should be working. If not, rinse and repeat the steps above. Sometimes it takes a cycle or two of this manual MOX intervention to get the audio flowing the way it should. 

If you're trying to use DXLabs to key the rig for you, give VOX a shot, which has worked well for me.
