jack.udp may be used to transmit audio between two computers, each
computer running their own jackd.
My understanding, based upon earlier threads in the linux audio lists,
is that to avoid xruns due to clock drift in this situation, the sound
cards of the two computers must be synchronised in some way, e.g. using
word clock.
Is this (still) correct? Or has jack.udp been developed to include
synchronisation?
(On a side note, it seems that Rohan Drape's web pages that are linked
to from the jack pages, http://www.alphalink.com.au/~rd/sw/jack.html,
have disappeared.)

http://netjack.sourceforge.net is there to fill this gap...

Thanks!
I read the README and had a look at the source, but I have not fully
understood it. I am especially interested in how you keep the two parts
synchronized.
It is said that jack_net is a backend that "takes on the role of a sound
card". Does this mean that this "virtual soundcard" will govern the
clock frequency with which jack is running? And is this the means by
which the two jacks is synchronised? (I.e., that the second jack is
governed by the rate with which data arrives over the network?)
There is also an alsa_client, which does some resampling, it seems. Is
this used as part of the synchronisation?
With kind regards
Asbjørn

Do you by the way have any experience with jack.udp, and can tell how it
is synchronised?

jack.udp does not synchronize at all.
thats why it misses packets if you dont wordclock sync both soundcards.
