Hi all, as an idea to get jackdbus stopping and then startup again I used as Edward Schrober suggested :
sudo kill -9 4327 (the number is the pid of jackdbus) but to no avail, jack won't start again. Now I'm on xfce, default for ubuntustudio. So it is not gnome related, but a more general configuration issue I think. grtz, Bart http://www.bartart3d.be/ On Twitter <https://twitter.com/#%21/Bart_Issimo> On Identi.ca <http://identi.ca/bartart3d> On Google+ <https://plus.google.com/u/0/b/116379400376517483499/> 2015-08-13 9:00 GMT+02:00 bart deruyter <bart.deruy...@gmail.com>: > Hi all, > > I'm running ubuntu 15.04 now, gnome variant, with ubuntustudio and > kxstudio installed through software sources. > > My soundcard is an Echo Audiofire 12, connected with firewire. > > Since 15.04 when I start jack it works fine as long as I don't run any > other application which requires sound, before starting jack. > > it is consistently going wrong when I for example start chrome, exit > chrome and try to start jack, using claudia, or qjackctl, or commandline. > the message qjackctl throws is: JackServer::Open failed with -1 > > When I log out of the system, then log in again (no reboot required) it > works again, as long as I start jack first. > > Also, when I use chrome while running jack things seem to keep working, > though I have ben thrown out of jack too. > > - I checked if I was in audio-group, which I am, otherwise it wouldn't > work at all. > - I turned autospawn off for pulseaudio and killed pulseaudio befor > starting jack > - tried out various settings in qjackctl. > > None seem to have helped. > > How can I trace the source of the problem?
