I am pretty new to the whole linux audio thingy... I dabbled in it for a bit some ten years ago... but never really got anywhere.
I am somewhat experienced with linux as my OS of choice though...
So here is what happened:
I downloaded the KXStudio ISO and installed it on my machine. After it was done, I let synaptic run all the updates and installed the pulseaudio-module-jack and the driver for my nvidia graphics card.
After that I wanted to start with some simple voice recording.
But as soon as I set the Output device to my external soundcard (Samson Studio GT... a rather simple USB audiointerface... basically a pair of speakers with two microphone inputs that connect via USB) jack won't start anymore.
The log shows this:
