Right. The audio department only needs to know the (ART, ptp) offset. The kernel and user space never need the (ART, mediaclock) offset. That is private information for the DSP. As long as user space reads (ART, ptp) and provides this regulary to the audio DSP, then the DSP will have all the information it needs to figure out (ptp, mediaclock).
