The pulseaudio daemon needs to be launched on thin clients in order to handle sound output by applications on the LTSP server. Package ltsp-client-5.1.0-0.3.20080310.fc9 usr/share/ltsp/ltsp-init-common: /usr/bin/pulseaudio --system \ --disable-shm \ --no-cpu-limit \ --resample-method=trivial \ --high-priority \ -L module-detect \ -L "module-esound-protocol-tcp auth-anonymous=1" \ -L "module-native-protocol-tcp auth-anonymous=1" \ -L module-volume-restore \ -L module-rescue-streams \ -L module-native-protocol-unix \ -n & It might be as simple as finding the right parameters to call pulseaudio.
No need to pass --no-cpu-limit. It is a safety measure that should not be disabled. Why no module-hal-detect instead of module-detect? Why disabling auth? Please use "pax11publish" to store the auth cookie in the X server. And use module-native-protocol's cookie argument to make it use a cookie in a very specific place. Make sure to remove the cookie file before running PA, to make sure people from a previous session may no longer connect. module-volume-restore would store settings globally for all users. Probably not what people want. Consider removing it's data files before running PA. That way you get volume restoring during the session, but not across sessions. No need to load the unix version of the native protocol unless you have local clients. Why use & instead of -D? --disallow-module-loading is a good idea.

Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
It is working by default in Fedora 9, however Lennart's suggestions in Comment #1 still need exploration to further lock-down the network access.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '9'. 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 9'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 9 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
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
