KX3 - WSJT-X with Raspberry Pi 5 and DigiRig sound card (CP102 and CM108 audio chip) fails TX audio

 

I have working KX3 + DigiRig with my Maclogger program and WsJTX on my Mac computer.
When I setup my new RP5 with DigiRig the audio decodes on FT 8 (in WSJT-X) but when I key the KX3 in USB mode ( audio modulation ) the radio will key but it seems the transmit audio goes out through the HDMI driver and out its speakers instead of into the mic jack.?

I used the ALSA tools and LSUSB command and the Cp102 + CM108 audio chip show up correctly. I cannot get the CM108 to take priority over outputting the FT8 audio which goes to the HDMI audio on my LED monitor.

The apparent rule of muting all output channels seems to apply to my trying to get audio out and into the mic jack on the KX3.

Since this a working system I can only conclude I am missing some tool to change the priority of increasing the driver ahead of the HDMI audio driver in the Raspberry Pi 5 OS.

Anyone have any suggestions how to get the settings right. I have been through several good articles on the RPi site by Philips and USB audio cards by Lady Ada to no avail. This has to be entwined with the fact the analog headphone port went away with the advent of the RPi5 and I cannot find a tool as the ALSA mixer won’t allow me to change the audio stream.

Hello John,

You need to install "pavucontrol" program and then do the following:

?? - start up wsjt-x
?? - have it start transmitting
?? - start the pavucontrol program
?? - in pavucontrol, go to the playback tab, see where wsjt-x is listed, and change the pulldown to use the desired output sound device
