Suggestions how to do that in a clean way?
Given that -audiodev is qapi-based I tried it this way:

--- a/qapi/audio.json
+++ b/qapi/audio.json
@@ -419,3 +419,22 @@
     'sdl':       'AudiodevSdlOptions',
     'spice':     'AudiodevGenericOptions',
     'wav':       'AudiodevWavOptions' } }
+
+##

+#
+# TODO
+##
+{ 'struct': 'AudioConfig',
+  'base': 'Audiodev',
+  'data': {
+    'model': 'AudioDevice'
+}}

But qemu doesn't like the schema:
qapi/audio.json: In struct 'AudioConfig':
qapi/audio.json:436: 'base' requires a struct type, union type 'Audiodev' isn't

We could easily support the case that no additional options are
specified, like this:

+{ 'struct': 'AudioConfig',
+  'data': {
+    'driver': 'AudiodevDriver',
+    'model': 'AudioDevice'
+}}

But then you have to switch to the long form as soon as you want
specify any audiodev config option.  Maybe that is ok, dunno how
much configuration options -nic supports.

take care,
