to sync your internal audio card to an external
ntp server. This accuracy pretty
much requires a HW ntp server. As I said the intel i210 ethernet cards at
$60-ish seems to be about the cheapest route.
It think it should be PTP [1] instead of NTP above, the latter is not accurate
enough. PTP can also be run in software timestamping mode,
hardware timestamping will be
more accurate, though [2].
I am not aware of anyone managing to get sw mode to be accurate enough to
derive wordclock from.
