Mic Audio Just stop working

Win 11 / SmartSDR v3.6.8 Using Mic connected to the computer.
I got on my Flex 6400 a few days ago and could not TX. I have no TX audio. I check the mic and it works on other programs but can't get it to work on the flex anymore. I check for all updates, removed it and re-installed it. I have been off the Flex for a few months and thought I just have something set wrong but if I do, I cannot find it. Any idea's

    Well, I thought this was a computer issue, but I just tried my iPad and I have the same issue.

    I believe most PC equipment uses TRS type plugs (tip+ring+ground) and iPads use TRRS type (tip+2-rings+ground). Have you checked PC microphone input settings. MS update my have changed settings.

    You need to be sure that you have PC selected and that DAX is off.

    To use a mic plugged into the computer, you need to set it as the default recording device.
