Created attachment 421070 [details] Log When playing sound using banshee and totem for example, the sound skips for a second every few minutes. I have run pulseaudio in debug mode and found some underrun is happening when the sound skips: ... I: alsa-sink.c: Underrun! I: alsa-sink.c: Increasing wakeup watermark to 30.00 ms D: protocol-native.c: Underrun on ''Princess Of The Dawn' by 'Accept'', 0 bytes in queue.

I have not really noticed this until now because I have not used this box for music, but it is very distracting now. Are there any tweaks I can try to work around the problem? I may be able to test F13 on this system (LiveCD), but a full upgrade is not possible ATM. $ rpm -qa | grep pulse pulseaudio-module-gconf-0.9.21-5.fc12.i686 pulseaudio-module-bluetooth-0.9.21-5.fc12.i686 pulseaudio-0.9.21-5.fc12.i686 pulseaudio-esound-compat-0.9.21-5.fc12.i686 pulseaudio-libs-0.9.21-5.fc12.i686 pulseaudio-gdm-hooks-0.9.21-5.fc12.i686 alsa-plugins-pulseaudio-1.0.22-1.fc12.i686 wine-pulseaudio-1.1.44-4.fc12.i686 pulseaudio-libs-glib2-0.9.21-5.fc12.i686 pulseaudio-utils-0.9.21-5.fc12.i686 pulseaudio-module-x11-0.9.21-5.fc12.i686
After browsing around a bit I first tried this: default-sample-rate = 48000 default-fragments = 8 default-fragment-size-msec = 10 Followed by high-priority = yes nice-level = -11 Neither had any effect.
I managed to upgrade this box to F13 and the problem seems to be gone now. You may want to close as CURRENTRELEASE or something like that
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
