VirtualBox only supports pulseaudio...
Are you sure about that?? I used VirtualBox here, and don't have pulse
installed. Virtualbox uses alsa here just fine.
I guess not 100% sure, but I definitely remember reading on one of
their forums one time that they intend to maintain active support only
for pulse.
Audio for my Vbox does work without PA.
