That's interesting to know. It would probably be up to projectacrn to submit virtio-audio to the committee, or at least reserve the device number. Do you have a contact at projectacrn that can help with this?

Thanks, that's useful. Xionghu, is there a public spec for virtio-audio, and/or does Intel intend to contribute it to the virtio specification? Unfortunately device id 21 is already taken. I'll send a patch to the specification that reserves id 25 for virtio-audio.
