I'm listening to music from an AROS virtual machine in VirtualBox. The audio setup is the following: AROS -> ALSA (loopback) -> zita-a2j -> JACK VirtualBox has no direct support for JACK. A bug was opened 3 years ago asking for jack support https://www.virtualbox.org/ticket/6049 This seam pretty hopeless, unless someone competent enough, which I am not, contribute with some patch. However, when listening to music, it works fabulous with my setup. The main advantage of VirtualBox is that the guest OS is really installed in a virtual machine, and any software compatible with this OS can be installed and will run. VirtualBox is also a little bit faster than wine. So my question is, are there anyone who tested VirtualBox with windows and some VST? Dominique -- "We have the heroes we deserve."
