Re: [LAD] Failed to connect to session bus for device reservation

Hi Guys, I’m trying to set up a minimal audio system (without X11) based on the ubuntu mini-iso. When trying to start jack, i get this dbus error message: ... sudo /usr/bin/jackd -p512 -dalsa -r48000 -p64 -n2 -D -Chw:MADIFXtest -Phw:MADIFXtest jackdmp 1.9.10 Copyright 2001-2005 Paul Davis and others.

Cannot initialize driver JackServer::Open failed with -1 Failed to open server ... I’ve seen others mention the error but have not really found a solution. I guess part of the problem is that I’m not really sure what the error means :-) So if anyone could be so kind to enlighten me?
