Using DAX Audio RX1

W5AP

Although my DAX control Panel v2.3.9 shows Slice A Streaming, I'm unable to input the audio to any program such as MMTTY, MixW, or FLDIGI
I get an error message "The sound card you have chosen (DAX Audio RX 1 (FlexRadio System is already in use or does not exist or does not support wave format.     The sound card operation is disabled"

How can I fix this?  Is this the result of something Windows changed?  Used to work fine

Probably you have issue with DAX drivers in your system after update, check Device Manager and your Audio  with View selection - Show hidden device
In case many double/hidden entries in the Device Manager, you should delete unnecessary and in case necessity reinstall DAX drivers  as described here https://helpdesk.flexradio.com/hc/en-us/articles/204017069-How-to-Manually-Re-Install-DAX-Drivers
