DAX problem...Flex6500, DXLab Commander, WSJT-X all worked
perfectly until a few days ago...            then
the following screen shots occurred and WSJT-X
no longer Receives signals

Software – SDR v. 2.4.9, Windows 10 Pro with latest updates

Windows – Sound – defaults:  Recording:  DAX Audio RX1, Playback:  Speakers/Headphones

Control Panel – Device Manager – Audio devices show the correct 28 total DAX entries and NO            hidden entries...

DAX files have been removed and reinstalled multiple times without success...

SmartSDR has been completely removed and reinstalled multiple times without success...

DAX panel shows TX and RX streams working, but IQ Streams with Driver Error

WSJT-X - Settings – Radio, Test CAT and Test PTT work correctly

Help!!  Could there be some residual Windows Registry fragments that are causing this?

Thanks for any advice, Mike, K6DRY

Hi Michael,

Looks like you are the victim of a Windows 10 update.

Please follow the steps in this post by Neil, K3NC. It will straighten out the DAX drivers.

The answer is in what you wrote about Windows sound defaults. DAX devices must NOT be Windows default devices. This is what produced the DAX driver error: It was being used by Windows and is not available to WSJT-X.
