Everything seems to work very well now. So I coninue to setup my system (graphical menu, browser etc). then just added the lines @audio - rtprio 99 @audio - memlock 250000 @audio - nice -10 ... I get the expected output 99.So, it seems it is related to X, somehow, or some program run at X startup.

I get audio dropouts and skips associated with ANY cpu usage.

The ´>>´ changes that to appending that echo to the end of the two files in /etc/security.

I'm having the time of my life with UbuntuStudio. Any new user created after that will have to be added to the audio group. Ardour2 and Ardour3 can be setup to run without trying to lock > memory or use realtime, but it is not a good way to run things.

Error: Jack: Cannot Use Real-time Scheduling (rr/5)(1: Operation Not Permitted) This is what I was missing, thanks!! Add User To Group Linux AFAICT the idea that messing with niceness was relevant to latency is one of those baseless rumors that spreads like wildfire around the Internet from time to time.

Thanks a bunch! navigate here Everythings works, even jack with rt and memlock with my normal user. Copyright 2004-2012 Grame. You are currently viewing LQ as a guest.

Older versions require the -R option to request RT scheduling. I want realtime and memory lock enabled to better performance (I use wine and reaper and my projects have a lot of channels and plugins) Thanks! The ´echo´ command normally just ´echoes´ whatever you type on the keyboard back to standard output, normally your PCs monitor.
