Well I'm currently testing this to be sure but I think my issue is with the "priority" setting of jackd, apparently is has to be above 50? Currently from the ubuntu repository it defaults to 0 (I think...maybe I changed it but not sure why I would) and makes me wonder what use it is having a value like that. Is there any time that a person would want a priority of zero, or anything less than the "magical" number of 50? Again, I don't know much about all this stuff so I'm always trying to piece it together as I go. Anyway, I've been trying for a long time to get a good linux audio setup and I think I've finally done it! Thanks to everyone who works so hard on all this great software. :) grae On 2/22/07, grae <drunkenbird@xxxxxxxxx> wrote:
Hello list, jackd is shutting down (seemingly randomly) with the message "zombified - calling shutdown handler". I am using: ubuntu feisty latest updates with ubuntustudio packages Dell Inspiron 630m laptop, 1g ram, pentium m 1.73 ghz Edirol FA-101 firewire qjackctl 0.2.21-1 jackd 0.102.20 libfreebob 1.0.0-3 kernel 2.6.20-8-lowlatency I added the following to limits.conf for pam stuff (I think) @audio - rtprio 99 @audio - memlock 250000 @audio - nice -10 jack startup command (from qjackctl, I've tried different settings with sporadic results) jackd -R -dfreebob -dhw:0 -r44100 -p512 -n2 -i10 -o10 I'm really lost as to what the problem is (I'm no linux guru) and my settings are only based on copying and pasting from guides around the net.
