pulseaudio and kvm...

Guys,

It seems that when I play a utube video clip in my web browser, my kvm 
virtual machine looses the ability to play sound. I have to shutdown 
firefox, before the virtual machine will then play sound. I was 
wondering if the kvm virtual machines are configured to use alsa or 
pulse audio? Or do they grab the audio device directly?

Cheers. Steve.
