thanks to your comment, I think I`ve done it right.
Since you're using Jack I assume you know the basics...
which include that you have to connect things (which
can be automated of course).
So for the record, here`s what I did:
– start Jack on both machines using qjackctl
– run 'zita-j2n ip-of-the-reciever 7000' in a terminal on the sender
– run 'zita-n2j ip-of-the-reciever 7000' in a terminal on the reciever
– bring up qjackctl`s connections window on both machines
I want to send Ardour`s output over the network so:
– on the sender, left side of the connections window,
flip ardour open and on the right side, flip zita-j2n open;
drag and drop ardour`s Master/audio_out 1 onto zita-j2n`s in_1;
do the same for Master/audio_out 2 and in_2; now, a line is
connecting these two channels
OK, you could also make the connection in Ardour.
– on the reciever, left side of the connection window
flip
zita-n2j open and on the right side, flip system open; connect
zita-n2j`s out_1 to system`s playback_1; do the same for out_2
and playback_2
OK.
So far, so good. It worked. I get sound through the
reciever`s headphones,
but it`s very very bad quality, something like an ultra low bitrate. What
I suspect is happening is, a lot of packets get lost and are replaced with
silence (zita-nj does this, right?).
Yes. You could try --buff 100 on the receiver. This will provide 100 ms
of extra buffering.
I originally tried it with using wifi connection
although I know it`s not
supported. Because of that, I tried it using an ethernet cable. I can`t
hear any difference. How can I debug this and possibly make the connection better?
Hmm, did you just connect the ethernet cable and then use the same IP
addresses ? In that case you're still using the Wifi...
Are you using Jack in real-time mode (this is absolutely essential) ?
Check the top line of qjackctl's display, it should show 'RT' in
the top line (just left of the % CPU indication).
