I just installed UBUNTU on virtualbox uses Win XP as host. There are no sound, what's the problem? my card is Intel 82801AA AC 97. What's wrong with these picks I can choose from devices menu on virtualbox:

Host Driver :NULL Audio Driver
Controller: ACH 97

Host Driver :NULL Audio Driver
Controller: Soundblaster 16

Host Driver :Windows Direct Sound
Controller: ACH 97

Host Driver :Windows Direct Sound
Controller: Soundblaster 16

So Which is correct should be to have sound on ubuntu. and what should be marked in volume control panel, I am tryning ALSA mixer but probably there are some problems ...

Maybe somebody have had same problem? Appreciate of answers

VBox 2.1.4
