No, that's not it.  On the host machine, there is no Pulse.  I removed it by 
hand.  Speech works fine without latency or crackling.  The problem only 
happens with sound coming from the guest with KVM.  It happens whether I'm 
in X or not and even if I use the -curses option to KVM.  The live CD in 
question doesn't have Pulse or Speech Dispatcher, only ESpeakup.  It's 
designed to be a command line rescue CD without X and it works fine when 
booted on the host.  It's obviously an issue with KVM, so perhaps slightly 
off topic for this list, but it would be nice to spin up a VM with Fedora, 
for example and not have the latency when using Orca within the VM.
