I'm not working on it but please feel free to CC me on discussion and patches. I have a general interest on Virtio IO implementations at the
moment.

Sure! (Though I should mention = that I do not know a lot about the virtio
architecture yet. I am = still reading up about it. So most of my mails might
be (silly) q= ueries. Though I hope to learn about it soon and send in
some pat= ches and tests :)


Are you planning to make it an in-QEMU device or maybe a external
vhost-user daemon?

The project page states t= hat we need to use the QEMU audio subsystem
for playing and capturing audio samples. I am not entirely sure if this im= plies
that the device should be an in-QEMU = device or if it could be an external daemon.
What do you suggest?
