I don't understand this response. I am not an experienced programmer with respect to these platforms and have no control what Virtual Box presents back to the OS. I will say that this problem effects multiple distributions. Particularly Kubuntu-KDE, Edubuntu, Lubuntu, & Xubuntu. Luckily, the following distributions are not impacted, Ubuntu Gnome, Ubuntu-Unity. Ubuntu-Studio. If there is a interface problem between the Audio support software and hardware/visualization, those issues need to be resolved between those two owning groups. I would recommend the development team research the differences of how Audio is treated across the platforms that fail vs the ones that work. I am sure there is differences and there is something going wrong in the ones that are failing. I would also guess that it is not likely that Virtual Box is the direct cause because the list of work distros runs on the same Virtualbox platform that serves the failing distros.
