trusdx-audio and CAT on Linux

[LILO]

Hi guys!

Tried to set up USB CAT and Audio today. There seems to be no single topic on forum concerning this. Or am I bad in searching? If so, pls move it to the appropriate thread.
So, here is my 5 cents for (tr)uSDX USB CAT&Audio and Ubuntu 22.04.

Latest beta FW 2.00x
Ubuntu 22.04

Everything was set up according to https://github.com/threeme3/trusdx-audio except for proper audio devices. For some reason (haven't dig into details yet) trusdx-txrx.py is not able to select correct in/out devices. So, you have to use pavucontrol (pactl, pacmd probably if you don't have GUI?) to choose TRUSDX as output and TRUSDX.monitor as input for python script. You could also tune RX/TX volumes here, in my case approx 75% was fine for both.

WSJT-X was tested. Works just fine.
Rig: Kendwood TS-480
Poll Interval: 10
Serial Port: /dev/pts/1 (could be 2,3... check ./trusdx-txrx.py output)
Baud Rate: 115200
PTT Method: CAT
In Audio tab: TRUSDX as output and TRUSDX.monitor as input

In case of different program that doesn't offer in/out audio devices selection you could use pavucontrol to assign it.

export PULSE_SINK=TRUSDX PULSE_SOURCE=TRUSDX.monitor && ./trusdx-txrx.py

Is a simple trick to assign in/out audio w/o pavucontrol
