fldigi sound problem on ubuntu 24.04 #fldigi #ubuntu

 

I have successfully installed Fldigi 4.2.03 on Ubuntu 24.4

I have good rig-control between Fldigi and my transceiver.

But I am unable to get audio from my transceiver to Fldigi.

?

I do have audio from my transceiver to my computer because I can see it on the Pulse Audio Volume control bar-graph.

?

Ubuntu 24.04 uses Pipewire for audio, but W1HJK indicates that this is not an issue with Fldigi.

?

On Fldigi configuration/Soundcard/Devices I select PulseAudio but I have no clue how to determine the Server string. Therefor this is probably the issue I am facing.

?

I have looked up Server string in the file fldigi_def.xml

<PULSESERVER></PULSESERVER>

Putting that in for the Server String field on the configuration window, I get a Pulse Audio error: “Connection refused” “Is the server running?”

?

But there is no PulseAudio server in Ubuntu 24.04

?

Anyone have any ideas about getting the audio into Fldigi?

?

Thanks.

Hi Bill

IME a PulseAudio server string is not needed except in special cases. (like connecting to a server on another machine)

My first thought is that fldigi is defaulting to another sound card source, that isn't the rig. In my Pavucontrol for example the recording tab has a pulldown source selection for the PC sound card and the Icom. Might yours be set wrongly? eg the internal PC sound card rather than the rigs. (however your hardware is setup) Oh and also check the recording source isn't muted.

Also check for input on fldigi by toggling the WF, FFT & SIG button. You may have to adjust the waterfall offset and range values. (between the WF and x1 buttons.

Bob, I much appreciate your quick reply.? I think you have found my problem.
I never thought about the recording tab as having the effect that it does.
The pulldown was set to "Monitor of PCM2903C CODEC"
I changed it to simply "PCM2903C CODEC" and that solved the problem.? I now have audio to Fldigi.
I will have to look up what the "Monitor" function is!!!
Thanks again so much for your help.

Adrian,
Thank you.
That Soundcard/Devices tab must be in a later version of Fldigi than the 4.2.03 version that I have.? I don't have the pipewire selection available on the tab.
But I will keep it in mind when I can upgrade.?
As of now the latest .deb file I can access is for Fldigi 4.2.03.? I see that a 4.2.06 tar.gz file is available but I am not sufficiently knowledgeable to build an installation from it.? So I will have to wait until a later version is available in .deb format.?? Or I will have to learn how to install from the tar.gz file - maybe give it a try soon.
Thanks again,
73, Bill, K4AJ
 

Adrian, Yes indeed.
