Turning back to the original thread I started: @ Mike Holstein:
my mistake I set the examples in the wrong order, usually I do first exit jack, don't hammer on it.* It is not the biggest issue.* Any way it happens, exiting jack and trying to start it again, even when I keep the device on, I don't get jack working anymore. And it's not my first day using ubuntustudio, I'm not a beginner, using it sort of hapily for 7 years now, so I do have some experience. Until now I never had any problem with exiting jack to start it again later on. Secondly I do use the internet to communicate too, not just to browse around a little, talking to other people who make music, browsing for samples, etc... I do not intend to invest in a second machine and I do expect my computer to handle audio work and some simple tasks as typing a letter of browsing the internet. I simply don't have the funds for it and I don't want to scale the philosophy of "for each task a different program" up to "for each task a different computer". greetz, 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 17:46 GMT+02:00 bart deruyter <bart.deruy...@gmail.com>: > 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.
