I'm not sure where this belongs. I created a Fedora Jam virtual machine in Virtual Box. I can heard sound out of the speakers when I watch a YouTube video. However, when I attempt to create a project in Ardour, I get an error message stating that it cannot connect to the midi engine. With Ubuntu and Debian, this means that the audio driver setting in Virtual Box is not correct. I tried all of these settings, to no avail. Any suggestions, so that I can test Fedora Jam?
