Hallo everybody! I have spent some time on googeling arounf and trying around to get Ardour3 running, but with no luck. The Error Ardour gives out is the following: [ERROR]: JACK: Cannot create thread res = 1 [ERROR]: JACK: Cannot use real-time scheduling (RR/5)(1: Die Operation ist nicht erlaubt) [ERROR]: JACK: JackClient::AcquireSelfRealTime error Actually this should be a common failure while starting jack, when the user does not have realtime permission, so I changed /etc/security/limits.conf and added the follwing: #@realtime - rtprio 99 #@realtime - memlock unlimited THen i created a group called realtime,to which i added me as a user. After that a rebooted. But still ARdour gives out exactly the same failure, so my question: How can i set realtime permission, so that i can use Audio-Software (Ardour3) and jack? My system: Opensuse 13.1. x86_64 Kernel: 3.11 i also started a discussion in, but so far no useful replies! https://community.ardour.org/node/7237?destination=node%2F7237 Thanks, Benjamin.
