Unfortunately this doesn’t work properly.
When using Wfview 1.1, the output audio from Wfview is not sent to wsjtx, while on Wfview 1.2e it’s the other way around, wsjtx audio is not sent to Wfview.
thanks, I will check again.
Which version macOS are you using, and which mac processor (M1, Intel)?
For Wfview I think 1.1, according to the screenshot.
