Hi!

I'm trying to use Jack with an Odroid-U3. I re-installed a Debian Wheezy
image which had Jack installed and was working fine with a Focusrite
Scarlett 2i4 sound card.

After compiling Pure Data I realized that Jack had been uninstalled (no
idea why), so I installed it again, along with Qjackctl, via apt-get.

connect(2) call to /tmp/jack-1000/default/jack_0 failed (err=Connection
refused)

jackd 0.124.1

In short, you've messed up your jackd installation. I have no idea what
you did to your sources.list or if you compiled jackd manually, but
you're clearly no longer using the jackd1 provided by Debian Wheezy.

Wheezy has version 0.121.3, yours is 0.124.1:

Also, Debian's jackd uses /dev/shm and not /tmp (line 58):

Just clean it all out (uninstall, rm, whatever) and go back to the
pre-packaged jackd.
