virtualization and speech

[Linux for blind general discussion]

Am I the only one that's running into an issue with virtualization 
software and speech? I'm running into qemu cutting out speech and 
virtualbox acting up with isos.

For instance. I was installing debian in qemu just now and the speech up 
and died. No worries, I'll use virtualbox.....nope. No luck with that.

So has nyone else run into that?
