I'm running headless Jamulus on a single core server on Linode on Ubuntu 20.04. I've launched a registered server and also a Jamulus instance as a private server thread ("sudo systemctl start jamulusPrivateServer01.service") on the same machine so both are running at the same time. One group needs to use the private server with about 15 connections. On the public side, I'd be running the registered instance with default 10. There will be overlap in the time both the public and private side will be...

Solid State Logic SSL2+ USB Audio Interface: I'm using the SSL2+ on a WinTel 10. Flawless integration with Jamulus. The ASIO driver from SSL is perfect. Nothing else needed. Inputs and outputs enabled me to easily integrate the unit into my home studio. I especially love the monitoring capabilities. I rate it as excellent. I'll try it on the Mac when I've got a moment. Apogee Duet: I have a Macbook Pro running a Duet (I've had it for a number of years). Works fine with Jamulus. Nicely configurable...

I'd recommend checking the setting on your ASIO4All. A couple of weeks ago, I helped a user who had that kind of issue with an external sound card -- the Focusrite. He runs Windows 10, also. I discovered that the ASIO4ALL setting included not only the Focusrite, but the internal sound card. After we disabled (unselected) the internal sound card, everything worked as advertised (low latency). We also made sure Windows 10 was working with the Focusrite. Give that a try, if you haven't already done...

Answer: Suggestion ... Use a separate device with video capability, like a tablet or old mobile device running Zoom. Point it at the screen.

I don't think either approach you've proposed will work. Whenever I've attempted to run Zoom and a Jamulus server, the latency explodes (putting Zoom on the server side). I believe audio is processed by Zoom (somehow) and is routed through everything and that increases the latency. I always got red lights. I also tried using a video switcher on the server side. It just didn't work. The solution that works for me (regardless of the server selected and being used) is to take the output from the Jamulus...

Clarification for users (including me) who are new to Linux and the command line: "--licence /" is included on a line in the jamulus.service file.
