Solved! The symptoms were
- IC-7300 audio devices (Burr Brown CODEC) not listed in WSJTX under Ubuntu 20.04 - Ubuntu 20.04 running in Virtualbox on same machine showed the IC7300 autio devices just fine and worked. - QT audio test program also failed to show the IC-7300 audio devices So, the problem is that some installed audio thing seemed to be screwing up QT. After a few months of thinking and delaying, I finally got around to trying to fix the problem. - Remove Jack package and all it's dependencies - Remove other unused audio programs and libraries. - Didn't fix - Reboot, Didn't fix Took a look at apt autoremove package list and there were a _lot_. - sudo apt autoremove - PROBLEM FIXED! It's interesting that package autoremove was necessary I have no idea which of the dozens of packages actually caused the problem. jeff, wa1hco On Wed, Dec 29, 2021 at 4:57 PM jeff millar <wa1...@gmail.com> wrote: > I have more information about WSJTX IC-7300 audio device missing. > > WSJTX running on my Desktop Ubuntu 20.04 does not list the IC-7300 audio > devices named "Burr-Brown from TI Audio CODEC" > > But an Unbuntu 20.04 VM under VirtualBox running on the *same machine* > can see the Burr-Brown devices and works fine. > > My guess is that the WSJTX call to QT's availableDevices() function is > either setting the requested mode to an odd value or my Desktop Ubuntu is > configuring the ports to an odd value. > > This is a setup problem because I've used WSJTX on this computer for > years.
