5917,no audio device could be opened,Marco ,,"When I install ubuntu 9.10 or ubuntu 10.04 (alpha), at reboot, after installation ends, the following pop-up message appears (I have an italian installation):
""no audio devices could be opened. Selecting the null audio backend with the consequence that no sound is audible
ID erroreHostAudioNotResponding
Gravità: Attenzione""

The strange thing is that at this point not only audio device is not usable anymore in the host system, but also the whole gnome desktop (I cannot logout anymore). To fix this issue (both on the guest and host system) I have to reboot the host O.S.
No issues happen if I install, for example, ubuntu 8.04 (actual LTS version).
