4.1.20 Ubuntu 22.04 pkg possible portaudio glitch while switching modems #27

Open kingsqueak opened 2 years ago

kingsqueak commented 2 years ago

Running the 4.1.20 that ships with Ubuntu 22.04 LTS.

I run Jack for virtual audio using a SunSDR 2 DX as the rig.

Portaudio sees Jack in the fldigi config and I patch the input and output from the fldigi Jack objects via qjackctl (patch bay)

Runs solid on many modes, PSK, Olivia Thor etc

I select Domino EX11 and something glitches and drops the jack patch connections.

I re-patch the audio again and Domino works fine, but when I toggle modem to PSK-31 again, it breaks the patch connections again for both input and output audio paths.

Unsure if other modems are affected, just noticed this with Domino today and was able to reproduce it a few times.
