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?

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:

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)

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:

?Rick,
I also use fldigi 4.2.05 on a Pi4 using Buster. My system was stable for until I started using flmsg. With it running, fldigi would freeze every few days. Without it, I can operate two simultaneous instantiations of fldigi (FSQ and Thor) for weeks without problems.

This evening I was actually looking at the display when it happened. I had entered a command, and it timed out dues to open squelch, reported that in the receive pan then immediately aborted.

Anything I can look for to help troubleshot this issue?

No change with alpha.? In response to your first reply, I don't think I confused flrig with fldigi.? Section 3.1.4 of the flrig manual talks about the PTT-GPIO option, , and shows the menu that I believe I used in the 1.3-ish version.

?

I'm not clear about how flrig is supposed to be aware of the gpio command in the WiringPi package.? I can run gpio as a command and the gpio pins obey.? For flrig, do I need to start a daemon process, or compile flrig with the WiringPi library, or does flrig just fail if I ask it to set a pin and gpio isn't present in the system?

?

Thanks much for your help,

Eric
