I have never done any live streaming, but I have used OBS with Jack and Pulseaudio to record my Yousician session. > Current Setup > 2-3 Audio interfaces.

The code can be found here: > https://github.com/obsproject/obs-studio/tree/master/plugins/linux-jack I had the Jack support included in my OBS build. Works quite well.

That was going into PulseAudio via the pulsaudio alsa plugin. PulseAudio routed it to its Jack sink, which I have connected to OBS. My guitar signal would come from an USB audio interface, via Guitarix as another input to OBS. Sometimes I would also connect the clean signal directly to OBS. For me the only limitation was the limited performance of my laptop – a bit too much going on and I would get xruns in jack, corrupting the audio.

Is there another solution? You could use some audio plugins in Carla and control them via OSC or MIDI, if you have any MIDI controller (a MIDI keyboard, a foot switch or even a phone app). > 4) Even though it's a small setup I'd need some sort of session > management to bring up at least the jack side of things.

Carla as host, I am not familiar with compressor plugins.
