Especially interesting for me is question of PulseAudio, so I selected the appropriate process. Below is the output. LatencyTOP version 0.4 (C) 2008 Intel Corporation Cause Maximum Percentage fsync() on a file 110.7 msec 0.5 % Scheduler: waiting for cpu 81.1 msec 45.6 % Writing a page to disk 14.6 msec 0.1 % opening cdrom device 10.0 msec 0.2 % Executing raw SCSI command 5.4 msec 0.2 % Waiting for event (poll) 5.0 msec 15.7 % Waiting for event (select) 5.0 msec 7.7 % Userspace lock contention 5.0 msec 30.0 % Waiting for event (epoll) 4.0 msec 0.1 % Process pulseaudio (2998) Total: 3586.0 msec Scheduler: waiting for cpu 81.1 msec 99.1 % Waiting for event (poll) 4.8 msec 0.9 % Userspace lock contention 0.1 msec 0.0 % gnome-keyring-d compiz-manager gvfsd gvfs-fuse-daemo pulseaudio compiz Reproducible: Always Steps to Reproduce: 1. just use openSUSE? Actual Results: Big latency (causing PulseAudio hiccups) Expected Results: Smaller latency (PA working flawlessly) -- 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.
