Were everything described as audio enabled and tested? As far as I was aware
some devices required some soundwire rework to support soundwire microphones.
Is it finished? I don't see this linked here, but you state that audio
features "added and enabled".

Do we understand this correctly that, I presume, everthing that is more-or-less compatible
with previous platforms were added and enabled (with renames) but not _all_ ?

Probably some rewording is required.
