FLEX-6700 transmit on digital modes quit working

Doug

Had Fldigi and WJST-X working. But now neither produces any transmit audio out of my 6700 running SmartSDR v 3.0.27 under Windows 10. DAX Control panel shows blue TX and transmitting, but with TX Gain at 100, no audio level is shown with either program indicating transmission of digital data. Windows Sound control panel shows input level at 100% for DAX Audio TX. P/CW panel shows blue DAX. Slice A panel shows red TX and DAX channel 1. Fldigi shows Playback on DAX Audio TX.  However, MIC still yields transmit audio. Windows feature update to Windows 10, version 1903 failed to install on 8/29. (version 1809 successfully installed on 2/21/2019.) Most recent Windows Quality Update was KB4523205 for Windows 10 version 1809 successfully installed on 11/12/2019. (tested this on 80 m, 20 m, and 2 m.)

Did you check FLdigi and WSJT to make sure the setting pointing to DAX audio path has not been lost ? Andy K3UK

Thanks for the reply. I checked that Fldigi Audio Playback setting still points to DAX Audio TX. I also checked that WSJT-X setting still points soundcard output to DAX Audio TX.

Thanks for the reply.  Please clarify what is meant by "DAX Channel has turn RED."  On the DAX Control Panel, the TX icon had a blue background.  On the P/CW panel, the DAX icon had a blue background.

Again I'm going to say the weakest link in the Flex system is DAX. This software is flaky, sometimes it works flawlessly and at other times it's a pain to use.
