@mpjgregoire Yes, but since when I could get going we got the info that the other group already worked on the audio drivers via the rump drivers, the responsible person at nlnet and me decided together to retarget the project to a smaller scope. See https://nlnet.nl/project/Hurd-Audio/
> fine-grained access management to physical hardware.
I had expected that the audio-device itself would get done independent of that: the proof of concept already existed:
