Re: [LAD] NetJack question

I'm back on this project after a break but not making much progress.

I'm trying to get the sound from the input hardware on one Linux box to play
on the output hardware of a second Linux box on the same network.

I'm using Jack1, version 0.124.1 on both boxes.

On the Slave (input), I run

jackd -d net

On the master (output), I run

Jackd -d alsa

and then (in another terminal)

jack_netsource -H 10.26.7.90

where 10.26.7.90 is the IP address of the slave device.

.but the two devices don't seem to connect.

When I start jack_netsource on the master, the slave briefly sees some
activity and puts up

netxruns amount: 21ms

resync after freerun. 5

netxruns amount: 2133ms

netxruns amount: 21ms

master seems gone. entering freerun mode

and jack_netsource returns

Not connected

If I can get the two ends connected, I'm hoping I can use alsa_in and/or
alsa_out to achieve the end to end audio but, again, I don't know exactly
how to make this work.

Any help would be great.

0.121.2 is the version I got from ubuntu with apt-get install.

I removed that version and downloaded and built 0.124.1, however when I now
try to run

jackd -d alsa

I get back

jackd: unknown driver 'alsa'

What's going on?

Your system is missing the development version of the ALSA library. So JACK
was built without ALSA support.

What version of Ubuntu are you using? I am unable to believe that 0.121 is
the latest version available for any reasonably recent version of that
distro.
