The fact that we accept "pulseaudio" as an alias for "pa" and expect "file" instead of "wav" are an unfortunate implementation detail and a bug respectively. I have just posted patches addressing the latter[1], and I don't think the former should be documented even though it's technically accepted, especially considering that we're talking about legacy settings and we want users to use the <audio> element instead. For the SDL part, since we don't have to deal with any of the conversion shenanigans in that case, I would suggest avoiding the list and using something like Valid values are those accepted for the ``driver`` attribute of the `SDL audio backend <#sdl-audio-backend>`__. instead. But your version works fine too if you're keen on keeping it as is :) [1] https://listman.redhat.com/archives/libvir-list/2022-January/msg00738.html -- Andrea Bolognani / Red Hat / Virtualization
