[LAU] CPU Priorities at limits.conf

I order to use my audio applications (related to latency) more efficiently, I gave some priorities to the applications which are in the "audio" group by adding the lines below, to the file "/etc/security/limits.conf" @audio - rtprio 95 @audio - memlock 512000 @audio - nice -19 By doing this, to which application did I give the priority ? Alsa, Jack ... ? How is that defined in GNU/Linux ? I mean, Did I give this priority to all applications using the sound device or to the applications that are included in the "audio" group ? Who, what or which are in the "audio" group ? Thanks. -- Arda EDEN Cumhuriyet University Faculty of Fine Arts Department of Music Technology Sivas/TURKEY
