<div dir="ltr"><div><div><div><div><div>Hi,<br></div>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.<br></div>I
did an "apt-get update && apt-get upgrade" and then I installed
libasound2-dev and libjack-dev because I wanted to compile Pure Data
from source, and these packages are necessary.<br></div>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.<br></div>Now when I
try to run Jack through Qjackctl, with the same sound card, Jack starts
but after half a second it stops. Here are the messages I get:<br></div><div><br>
