[xubuntu] VirtualBox 5.0.24 no sound after xenial upgrade

Hi,

sound is not working on any of my virtual box machines (Linux and Windows).

Sound on the host is working and activated as before.

VirtualBox guest Linux/lubuntu settings:
- driver: PulseAudio
- controller: ICH AC97

On the guest, audio seems to work, I can see the visual output from pavucontrol.


Maybe it is a problem with VirtualBox Version 5.0.24?

Someone know a solution?
