Sound is not enabled in this scenario, but this is not necessarily 
surprising. I suspect the issue is that because of configuration changes 
done by Kubuntu the windows driver thinks that the device is not one it 
supports hence is not even loading.

I will try and find an iso image for this beta. I was also going to try 
the live cd for Karmic to see whether or not an older kernel has the 
issue, but I have to work around an issue that the live cd is not 
compatible with my monitor. I have an Acer AL1716 flat screen monitor, 
and when the Karmic live cd loads the desktop I get a black screen with 
a floating dialogue saying "Input not supported". From memory the only 
way to fix this is to switch to another tty session, login, and run 
Xrandr to change the resolution/refresh rate, but I will need to play 
around.
