Most probably something is using hw:0 in your system (pulse). Jack is meant to
use the hw:x direct interfaces to the soundcard, if something else is using it
then jack cannot start.

But this is also suspect, the default parameters might be wrong for your
soundcard (although the permission denied message would imply that the device
is busy - by the way, the one that is busy is the control device, not the pcm
one).

Jamin depends on jack running fine. This appears to be a problem starting jack
in your system. Try to start jack first, and if that is successful then try
jamin.
