[fedora-virt] Fedora 12 host and windowsXP guest - No Sound from guest

[Daniel Sanabria]

Thanks Cole,

with your comments things are starting to make a bit more of sense to me.

So I now see 2 options:

   1. start qemu with the user account which will potentially mean to stop
   using virt-manager
   2. Install/compile the gtk-vnc version that support the audio extension
   (only if it's already available)

Could you provide some guidance on how to approach any of these options?
i.e. How can I start qemu and the guest manually without using virt-manager?
or is there gtk-vnc version available that supports the audio extension?

Cheers,

Daniel
