I've been trying to get a foss virtual guitar amp to run on my Fedora machine for a while now, Guitarix (which runs on JACK) to be more precise. But I just can't figure it out. People say that it is very straight forward to get it to work by using AV Linux instead. I don't want to install a new distro on my machine, though. So my idea is to create a Docker image based on AV Linux and somehow pass my USB sound card adapter thingy (which I use to connect my guitar) through to the Docker container and then use a VNC tool to interact with the Guitarix GUI in the container. (I also have a normal USB sound card that could be used as the output device in case it would help reduce the latency.)  But my fear is that doing this with Docker would introduce a lot of audio latency, effectively rendering it useless. It is really important to me that the delay between picking a string and hearing the sound is as low as possible. A 100 milliseconds for example would be way too much already. 20-30ms would probably be acceptable.I have already tried it with a virtual machine and the latency was pretty horrible. I have to admit I was using a Windows VM with a different virtual amp (RockSmith) which is very CPU/GPU intensive, though.
Docker with real-time / low-latency audio? (for virtual amps like Guitarix...)
