If I understand it, the deprecation message suggests "-device ac97"
instead of "-soundhw ac97", but that in turn relies on the deprecated
default audiodev feature.

So I'm not sure deprecating -soundhw is a good idea.  Instead, is it
possible to make "-soundhw foo" desugar to "-audiodev
something,id=audio0 -global foo.audiodev=audio0 -device foo", where the
"-device foo" would be omitted for isa-pcspk?  It's all ad hoc, but
that's the point of combined frontend/backend options like -nic.

This doesn't change that libvirt can just stop using -soundhw just by
looking for the isa-pcspk.audiodev property.

Thanks,

Paolo
