Re: [ubuntu-studio-users] ubuntu-studio-users Digest, Vol 100, Issue 4
When jack runs it starts a process called jackdbus. If jack fails jackdbus hangs around as a zombie that needs to be killed before jack will restart. *ps -A |grep jackdbus* You will get response jackdbus (where is the process number) *sudo kill -9 *(I didn't check the process level that jackdbus runs, but -9 kills it!) Then jack will start just fine if it is setup properly.

Re: [ubuntu-studio-users] ubuntu-studio-users Digest, Vol 100, Issue 4
Perhaps you should run claudia on boot? Once you decide to use jack, it should be part of the environment - always there. If you use $HOME/.jackdrc jack will start with your user session. if you make a file /etc/jackdrc it will be the default jack session parameters for the computer. A clean Ubuntu-Studio install does not have these files. I think .jackdrc gets generated when you run qjackctl for the first time. I think claudia reads and writes ~/.jackdrc. There is a discussion about jackd vs jackdbus at http://jack-audio.10948.n7.nabble.com/more-jack-qjackctl-madness-td8914i20.html Which I have not yet figured out.

Re: [ubuntu-studio-users] ubuntu-studio-users Digest, Vol 100, Issue 4
thanks for the ideas, but again, these are not solutions. let me explain the problem again in real life: 1. I start claudia, run ardour4 for a recording, then I decide to stop after an hour. 2. I exit ardour, shut down my soundcard (remember: power-consumption) which kills jack, because it has no soundcard to run anymore, or I first stop the studio in claudia and then turn off my external soundcard. 3.and I go surfing a bit as a break. 4. Then I want to start again, fire up my external soundcard and I want to run claudia again to launch my apps, like ardour, guitarix, etc... 5. only to discover jack won't start anymore. 6. Only solution so far: log out and log in again I hope this explains the problem better. I don't want to have to log out each time I have done something else then audio-work for a while. I can't believe this is a normal thing to happen. 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 16:54 GMT+02:00 Kaj Ailomaa zeque...@mousike.me: On Thu, Aug 13, 2015, at 04:51 PM, Kaza Kore wrote: From: bart.deruy...@gmail.com Date: Thu, 13 Aug 2015 16:31:48 +0200 To: ubuntu-studio-users@lists.ubuntu.com Subject: Re: [ubuntu-studio-users] ubuntu-studio-users Digest, Vol 100, Issue 4 thanks for the tip.

thanks for the tip. I'll try using the pid to kill jackdbus, though I thought it was killed by right clicking in systemmonitor and clicking on destroy process. That did not help to get jackd running again by the way. I find it weird that it used to work in previous versions of ubuntu and not now. I run an external device as soundcard (audiofire12) and don't keep it on every day (I do mind to keep power consumption low, so I don't activate things when I don't need them) . Starting up with jackd running is not an option I'm afraid since my soundcard won't be on, and jack would definately crash. Ubuntustudio should be capable of running both internal soundcard and my audiofire. Using two soundcards is even described as a solution to have both jack and pulseaudio running, so it should work. 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 15:55 GMT+02:00 Edward A Schober t...@schober.us: Perhaps you should run claudia on boot?
