For me it works out of the box in the way that I can hear sound played  
inside the VM and the VM can record from the microphone attached to the PC.  

In virt-manager it appears as "Sound ich9" device added to the respective  
VMs. Host and guest both use Pulseaudio. In case you do not use GUI, it  
might be enough to add the following device in the VM's XML:

    <sound model='ich9'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x1b' function='0x0'/> 
    </sound>

I do not know if it can be made to work in a way that just a single pulse  
audio server is running -- in my configuration, the guest and host both have  
their respective pulse audio instances although the sound itself passes from  
the one to the other wihtout explicit configuration :)
