Thank you for the screenshots. Let’s deal with the sound card error first. I’ve seen this before when sound card gets disconnected, kicked out by RFI or reassigned to a new USB entity because of the changes to where it is plugged on the computer. Just go to the audio settings, re-select Digirig’s input and output components there, save the changes by clicking “ok” and then close the app. The error should be gone upon re-opening WSJT-X unless hardware configuration changes again.
Please let me know if the error is gone or not. We’ll then deal with communication error.
