After updating my OS from Fedora 36 => 37 (updated not new install)
The audiodevices have changed name or not found
previous it was something like hw:CARD=Loopback,DEV=0 (Wfview settings)
Not such selection anymore…a lot over others
And in WSJT-X is was previous like plughw:CARD=Loopback_2,DEV=1
No such selection anymore
Original configuration was with Qt audio
On OS basis it seems reporting the same 4 loopback devices and no difference is found in any sound config files.
Using 4 loopback devices because I somet imes run 2 instances of Wfview (IC7610 & IC9700)
Wfview is ver 1.64 build b4c079f, my own build but no change to code
A side observation is that portaudio and Rt audio is resulting in much higher RX latency compared to Qtaudio, also on Fedora 36…is that normal ?
Every operating system, library, and audio hardware will perform differently. This is why there is a selection of three different audio systems to select from. We could not determine that one was consistently better than the other for everyone.
When you consider the number of operating systems supported, and versions thereof, plus the sheer mass of possible audio products, you see why we left in some flexibility.
As to why, I haven no idea, but I do see sometimes that one system works better than another for me.
That is the challenge with Fedora…they update so often that they break working things which will be fixed close to EOL (maybe first in later releases).
It is more likely that a package can’t keep up with this pace and get broken due to new releases.
In this cases in was not so…I haven forgotten to note down an earlier fix to a problem.
At that time when I found that fix…F36 was a’live and the problem stays even in F39-F40
Loopback devices does not show up in useable way and need this fix.
update your setup to something more sustainable better tested environment. I tested wfview on F39 and F40. F39 out of the box and F40 after the update by the way.
Another platform…have taken a approach a few times but ran into other problems and as I have several machines running Fedora it is some what…you know and live with what you have.
But basic you are right about shifting distribution.
Your test on F39-F40…with loopback devices ?
They need the same fix otherwise there are troubles to get Wfview <=> WSJT-X, MSHV, FLdigi…tested
(KDE Desktop)
On F39 the wfview package made build downloaded from wfview web page
does not run on F39
“wfview: error while loading shared libraries: libcustomplot.so.2: canot open shared object file: No such file or directory”
qcustom package are of course installed
My own build run’s
I believe that was the reason I way back need to build wfview by myself
