Red Hat Bugzilla – Bug 885020
The pulse-rt group doesn't exist by default, causing round-trips to the SSSD
Last modified: 2014-11-05 15:59:33 EST
Description of problem:
According the man pulseaudio(1), "membership of the calling user in this group decides whether real-time and/or high-priority scheduling is enabled.".
Apparently, the group is requested via the Name Service Switch during playback and if other Name Service Switch modules such as sss for the SSSD are configured, the pulse-rt group is queried from them as well.
I don't think that correct, because this is causing unnecessary load on the remote LDAP servers and in some cases unnecessary reconnection attempts.
Is there a reason the group is not present at all on the system rather than being present but empty?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. play sounds
The requests for pulse-rt are bubbling all the way into the SSSD and then into the remote server query.
The pulse-rt group should be returned right away from libnss_files and only the membership in that group should determine the realtime playback.
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. 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bug reports from releases that are no longer maintained.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 '18'.
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 18's end of life.
Thank you for reporting this issue and we are sorry that we may not be
able to fix it before Fedora 18 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, you are encouraged change the 'version' to a later Fedora
version prior to Fedora 18's end of life.
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.
Thanks, fix committed to rawhide,

- Use the statically allocated UID and GID from /usr/share/doc/setup/uidgid (#1056656)
- The pulse-rt group doesn't exist (#885020)
Will likely get rolled into a f20 update sometime soon.
Really fixed for pulse-rt in pulseaudio-5.0-22.20141019git4971d.fc22
