So I'm completely confused by how audio is supposed to work
with spice. The spice-space.org
docs have various marketing
level blurbs talking about how audio is one of the channels
of data handled by the spice client, but playing with my
windows XP KVM machine on fedora 14, I can't get any audio
at all to play.
I'm also confused by all the examples showing I should start
qemu with an ac97 audio device. I would have expected an audio
equivalent of the video qxl driver (but what do I know?).
qxl is paravirt GPU that was specifically created to provide advantages
over the poor old Cirrus logic alternative.
For audio things are simpler, there is no need for pv device since the
rate is usually slow - 44khz +- That's why full emulation is still a
good idea and ac97 should be used.
Can anyone clarify for me the state of spice and audio
(and maybe even give me a hit about how to get audio
out of the Windows XP virtual machine?).
ac97 is the device/driver pair. Without spice you should use a host
'backend' like pulse. With spice, spice-server is the backend and it
sends the audio directly to the spice-client that plays the actual stream.
