fldigi stopped working on Raspberry Pi


 

I been using fldigi for years on my Raspberry Pi station computer. It worked fine until a few months ago. Since I was having a great time on SSB DX I let it go, but I would like to be able to use it again.
Symptoms:
  • The rig interface doesn't work, it will not cause the frequency to change, and it does not follow? the frequency on the transceiver.
  • fldigi does not interface with flrig. I tried that as an alternative and nothing. flrig controls the rig fine but fldigi does not "see" flrig.
  • There is no waterfall. It appears the audio is not getting to fldigi.
As a comparison, I ran JS8Call and QSSTV (I've forgotten it's real name) and they both decode correctly. JS8Call controls the rig.
?
fldigi is 4.1.20
flrig is 1.4.4
PiOS is Buster
Pi is a 400
I have attached screenshots of the rig and audio configurations.

I have run out of ideas on how to diagnose this. Suggestions please.
