-audio is used like "-audio pa,model=sb16". It is almost as simple as -soundhw, but it reuses the -audiodev parsing machinery and attaches an audiodev to the newly-created device. The main 'feature' is that it knows about adding the codec device for model=intel-hda, and adding the audiodev to the codec device. In the future, it could be extended to support default models or builtin devices, just like -nic, or even a default backend. For now, keep it simple.
