First of all, thanks, Xavier, for your comments.
I now got the hardware and I tried to set it up following this:
https://github.com/jackaudio/jackaudio.github.com/wiki/WalkThrough_User_Net…
Short story: It doesn’t work.
Long story: When I rung the 'jack_netsource' command, I start to get
resync-messages (see log at the end of the message). On both machines, nothing shows up in
the qjackctl-patchbay so I don’t know where to route my sound from machine A to B. I’ve no
sound so far on B.
I’d appreciate your help with this!

Hello JACK community,
I’m planning my new audio editing setup (both hard- and software) and before investing in
hardware, I’d like to ask for advice.
Here’s what I want to do:
– Both computers run Linux.
– On Computer A, I can browse the web and see Youtube videos, I can listen to MP3 files
with Totem and I can do DAW stuff with Ardour.
– Computer B does nothing more than getting all the sound output from A and feed it to
the speaker through it’s soundcard.
Here’s my theoretical approach:
– Both computers run JACK.
– A runs PulseAudio in top of JACK.
– A runs with the net backend using netJACK2.
– B has the Net Manager loaded which gets the audio from A and pipes it to the
soundcard.
– Every time I boot the two computers, they are ready to work. No daemons I have to
launch manually, etc. I want the configuration to be done one time for all.
I got my understanding of JACK through the network from here:
https://github.com/jackaudio/jackaudio.github.com/wiki/WalkThrough_User_Net… And this
site would also be my guide for setting up the thing.
But I’m not a JACK expert at all. It’s the first time I’m doing something like this. So I
want to make shure I got the basics right. And, maybe you now even a better step-by-step
tutorial which does exactly what I want.
So, I appreciate any comments on this.
Looks okay to me; this is the approach I'd take as well.
Some things to note:
- If computer A and computer B are connected by something other than cable, you might
want to use NetJack1 (netone) instead of NetJack2. The latter is still pretty fragile to
connections with packet loss or jitter, AFAIK.
- NetJack1/2 don't propagate latency, so you'll theoretically experience some
A/V delay when watching videos, for example. In practice, the difference is small enough
that I've never knew it was there.
My five cents.
Xavi
Bye,
