Audio TX driver error, remote site, version 2.4.9

KC4SW

environment:  remote site, Toshiba laptop, Win 10 Pro (64 bit with all updates), software 2.4.9

problem: Everything EXCEPT TX Stream installs and operates normally. TX Stream shows driver error. Sounds window shows TX Stream device ready and not "attached" to any thing.
Performing the "test" function located in the "Sound" window produces an
acceptable indication on the bar graph (it goes up/down).  Receive audio works normally and flows to WSJT, PTT also works normally.

Uninstalling, reboot, re-install per FAQs produces same effect.

Note: the local system (Win 10 home 32 bit, etc.) all installs and operates normally
(for the first time is 6 "installers" )
Remote DAX IQ shows busy and delivers the frequency the radio is tuned to
but does not stream data, I suspect this is normal as I am remote and the
associated ports are not open.

I would have opened a help ticket but the "Captcha" window is not showing on the help tcket page
