Loss of PSK and RTTY Tx audio from SDC with new DAX

in DAX
There have been several occurrences with at least 3 Flex users (both 8600 and 6600s) of the TX audio disappearing when switching between RTTY and PSK on separate slices. This either happens at startup of SDC or at some random time. The Flex still switches between slices when the appropriate QSO window is selected in SDC and it goes into transmit as expected, but there is no audio on the transmission and nothing on the Smartsdr audio level meter. This either happens to one or both of the modes. Restarting SDC or SMartSDR does not fix the issue. The only fix I have found is to shut down the DAX program. I have been unable to reproduce the issue if SmartSDR and SDC are run without DAX running. ( It appears DAX isn’t required to run SDC?)

I suspect there is a conflict between the new DAX software and controlling the Flex/SmartSDR via the API but that is just a guess.

Not sure if this is an SDC issue or a Flex issue so posting in both forums just in case anyone else is seeing this issue.
