I'm having a DenverCoder9 week. I'm trying to do exactly what was asked here 2
years ago:
http://comments.gmane.org/gmane.comp.audio.jackit/25893
Unfortunately, the discussion never ends with a report of success. Is it even possible?
Between that and info here:

https://github.com/jackaudio/jackaudio.github.com/wiki/WalkThrough_User_Net…
This is what my plan is:
JACK slave (on PC w/ speaker) Windows 7:
C: jackd.exe -R -S -d net
C: jack_load audioadapter
C: jack_connect netadapter:capture_1 system:playback_1
C: jack_connect netadapter:capture_2 system:playback_2
JACK master (Audio source/Line-In) Windows 7:
C: jackd.exe -R -S -d portaudio "ASIO::ASIO4ALL v2"
C: jack_load netadapter
In JackControl connect linein1->slave1
In JackControl connect linein2->slave2
In JackControl press the play button
I only get as far as the second step. When I try to jack_load audioadapter,
Jackd says Waiting for a master...
Ringbugger automatic adaptive mode size =4096
MMCSS API not used...
and then Jackd crashes within a second with

Jack seems like the perfect way to stream low latency audio around my house. I hope
it's just something simple that I'm doing wrong. Thanks guys!

Chris,
No, I didn't but after some experimenting I did now and it still crashes with a
connection. Should the jackd crash if there's no connection? I had to modify my
master's steps to the following to get a handshake.
C: jackd.exe -R -S -d portaudio "ASIO::ASIO4ALL v2"
C: jack_load netmanager
In JackControl connect linein1->slave1
In JackControl connect linein2->slave2
In JackControl press the play button
I do all of the above first now, and then on the slave:
C: jackd.exe -R -S -d net
C: jack_load audioadapter
The Master shows:
