Hi, I am seeing this on /var/log/messages: ... Feb 17 12:56:47 localhost pulseaudio[2741]: polkit.c: Failed to show grant dialo g: Unable to lookup exe for caller Feb 17 12:56:47 localhost pulseaudio[2741]: polkit.c: PolicyKit responded with ' auth_admin_keep_always' Feb 17 12:56:47 localhost pulseaudio[2741]: main.c: Called SUID root and real-ti me/high-priority scheduling was requested in the configuration. However, we lack the necessary priviliges: Feb 17 12:56:47 localhost pulseaudio[2741]: main.c: We are not in group 'pulse-r t' and PolicyKit refuse to grant us priviliges. Dropping SUID again. Feb 17 12:56:47 localhost pulseaudio[2741]: main.c: For enabling real-time sched uling please acquire the appropriate PolicyKit priviliges, or become a member of 'pulse-rt', or increase the RLIMIT_NICE/RLIMIT_RTPRIO resource limits for this user. Feb 17 12:56:47 localhost pulseaudio[2741]: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted Feb 17 12:56:47 localhost pulseaudio[2741]: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted ... So, what should I do exactly to fix this? Regards, Andre
