Windows 7 no audio after virtual box install

[richzilla]

Ive installed windows 7 on a virtualbox vm (ubuntu 10.10 host) and installed the vbox guest additions. Everything seems to have gone to plan, except for the fact that im missing any form of audio. Windows reports that it doesnt have any audio devices installed. Can anyone point me in the correct direction?
