DAX Error Problem

TxPres W5PD

I have been running WSJT=X on my Win 10 computer for several years with no problem.
When I turned it on today, I can start Smart SDR but I get a DAX Driver Error Dialog box.
Says an error has occurred while trying to open a DAX sound Device.
Looking at the DAX, the Slice A Rx stream box is blue and streaming. The IQ streams box 1 is blue and streaming. However, the TX Stream box is not blue.
On the Smart SDR screen, Channel 1 is shown on both DAX boxes. Also in the Radio pane the DAX box is blue.
I am receiving signals shown in the Smart SDR waterfall.
When I open the WSJT-X program, it says Error in Sound Input.
But I have not changed anything in the program settings.
Under Audio, Input is DAX Audio RX 1 and Output is DAX Audio TX.
I think the problem may be in the Win 10 Sound Device settings but I can't figure it out.
I have reinstalled Smart SDR 3.8.20
The Radio is a 6700.
Any help would be appreciated.

Found the problem. Somehow, the Microphone was turned off for all apps which caused all the problems.

I turned it on and everything works as it should.

Not sure if it had a Windows update overnight, or what happened. Fixed now.

Not the first time windows has changed the sound card settings on its own.
