Thanks David,

So I installed qpwgraph and when I run it I see a graphical display but I don't see any slider bars to adjust audio. I can see pipewire in my pulse audio volume control application so is it okay to use that? Here's what it looks like:



Also, in Fldigi sound card configuration do I need to select PortAudio, pipewire for my Devices?

Pipewire is supposed to emulate the API calls for pulseaudio.? I do not think that pavucontrol is compatible with pipewire.

When working with PipeWire, you can use audio mixer controls like "qpwgraph" (a Qt-based graphical patchbay), "Helvum" (a GTK-based patchbay), or Carla (a JACK-based mixer) to manage your audio routing and mixing, depending on your preferred interface and complexity needs; for more advanced audio processing, consider using dedicated plugins within your DAW or applications that support PipeWire integration.
Key points about these options:

??? qpwgraph:
??? Considered one of the most popular choices due to its user-friendly interface and Qt framework, offering a visual representation of your audio connections within PipeWire.
??? Helvum:
??? A GTK-based patchbay that provides a similar functionality to qpwgraph, with a slightly different interface.
??? Carla:
??? While primarily a JACK-based mixer, it can be used with PipeWire through the JACK protocol, allowing for more complex audio processing and plugin integration.

Thanks Dave, I will try the debugger.
I just did a new install on my new install of Linux Cinnamon Mint 22 using the WIKI. I followed the console and couldn't see what version of fltk it was installing.
Here's some notes I'm not sure about when I do the build:

****

sudo aptitude build-dep fldigi fails...

ny3j@ny3j-NucBox-G3:~$ sudo aptitude build-dep fldigi
Unable to satisfy the build-depends: Build-Depends: debhelper-compat (= 12)
Unable to apply some actions, aborting

so I continue to do sudo apt-get

sudo apt-get update
sudo apt-get build-dep fldigi

When I do the sudo aptitude install pavucontrol command I get the following:

ny3j@ny3j-NucBox-G3:~$ sudo aptitude install pavucontrol
[sudo] password for ny3j:??????? ?

The following actions will resolve these dependencies:

???? Keep the following packages at their current version:

???? Leave the following dependencies unresolved:??????? ?
2)???? pavucontrol recommends pulseaudio???????????????? ?



Accept this solution? [Y/n/q/?]

I choose Y to accept this solution.

The messages that I get about Pulse Audio and Pipe Wire have me nervous.

Same problem here with Debian 12 and fldigi 4.1.23 (latest in the mainline repository).? Locks up every few days with high CPU utilization.

It's the program, rather than some RFI or other environmental.?? Been there, have the t-shirt.? Too predictable for that, plus the OS and other programs run rock solid.

My guess is a Pipewire incompatibility as mentioned.? Will be checking out the potential flmsg connection.
