I am(was) using WSJT FT8 quite successfully for a couple weeks with my TS-590SG. Then suddenly this morning I start getting "Error In Sound Input" "An error opening the sound input device has occurred" during the Enable TX sequence. Then I am locked out of the program. And although not transmitting, the RED TX light remains illuminated on the 590. Thinking a file might have become corrupted I uninstalled WSJT, re-booted the computer and re-installed WSJT...same problem happens. I made sure that the audio settings are the same as the screengrabs I took when I first installed WSJT. Has anyone seen this? I just do not understand what it is trying to tell me. Actually, there is no microphone, or any other audio input connected, just USB CODEC speakers for audio out.
