I have the same problem - I have a working RPI-5 with DigiRig and WSJT-X + Winlogger on my Mac and the KX3+DigiRig+WSJT-X works 100% transmit and receive. When i move the to exact same configuration (unplug USB from MacStudio - Plug USB into RPi5) , FT8 decoding and all features TX etc. All work except NO transmit audio comes out of mic cable . ?I run the KX3 in upper sideband mode (USB) and have used RTS keying and there is no audio coming out the DigiRig into the microphone jack. Running in data mode makes no difference. I tried ALSA mixer control but it’s primitive and offers no ability to make the DigiRig chipset open up Xmit audio for the mic jack cable.?
Any ideas
thanks
