This becomes even more noticeable when there are other tasks running on the system that schedule activity in regular intervals (example: typing in a text editor that needs to do regular screen updates). The problem is caused by rtkit-daemon failing to get realtime scheduling for pulseaudio; in /var/log/messages we find: rtkit-daemon[1241]: Sucessfully called chroot. rtkit-daemon[1241]: Sucessfully dropped privileges. rtkit-daemon[1241]: Sucessfully limited resources. rtkit-daemon[1241]: Running. rtkit-daemon[1241]: Failed to make ourselves RT: Operation not permitted rtkit-daemon[1241]: Watchdog thread running. rtkit-daemon[1241]: Canary thread running. This bug is also discussed at https://bugzilla.redhat.com/show_bug.cgi?id=655321 ; it seems to be a problem related to systemd and the version of rtkit (0.5) that comes with openSUSE 12.1. Reproducible: Always Steps to Reproduce: Check if your pulseaudio threads have realtime priority. Actual Results: All pulseaudio threads have normal priority. Expected Results: There should be a pulseaudio thread with RT priority. The problem does not occur with the most recent version 0.10 of rtkit. As this probably affects most desktop users, is there a chance for an update? This could also solve other reported audio bugs; for example #671521, #677222, #551777. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
