Hi Felipe,

thanks for the offer.

I already contacted him a few weeks ago but got no reply.

I think jack, pulseaudio and ALSA would be more appropriate. For
Windows, there is already a virtual sound card driver, for example.

It is not a new protocol standard, but an interoperability standard that
involves existing protocols like RTP, RTCP, SIP and PTP and defines
certain usage profiles. There is no free Linux implementation that I am
aware of, yet. However, linuxptp can also be used to provide PTP data to
other devices in the network, which is why I started to work on a Debian
package.
