Another capability I'd like to expose is the functionality provided by qemu's 
audio-spice module, which IIUC is essentially `-audiodev spice`. After peeking 
at the qmp ref manual [1] I expected to find an "audiodev" object, however

# virsh qemu-monitor-command test \
   --cmd '{"execute":"qom-list-types"}' | grep -i audiodev
#
# virsh qemu-monitor-command test --cmd \
   '{"execute":"qom-list-properties","arguments":{"typename":"audiodev"}}'
{"id":"libvirt-411","error":{"class":"DeviceNotFound","desc":"Class 'audiodev' 
not found"}}
# virsh qemu-monitor-command test --cmd \
   '{"execute":"device-list-properties","arguments":{"typename":"audiodev"}}'
{"id":"libvirt-412","error":{"class":"DeviceNotFound","desc":"Device 'audiodev' 
not found"}}

Command line help is not available either, which spawned Claudio's qemu patch [2]

# qemu-system-x86_64 -audiodev help
qemu-system-x86_64: -audiodev help: Help is not available for this option

Have I overlooked alternatives for detecting `-audiodev spice` support?

Thanks!
Jim
