Just finished installing F10 with next to no problems. My only real

In "messages" I get

As the users that are using ldap are not listed in the user management,
how do I add these users to the "pulse-rt" group? I have no control
over the ldap groups that have to work across multiple versions of Linux
and other OS's.
I cannot even run the KDE setup for audio as "System Settings" freezes.

I think those 'error' messages in syslog are fairly typical and that you
don't actually need users in pulse-rt group at all.
is pulse daemon actually running on those machines? as user? If so, can
the user open 'Pulse Audio Manager' application (multimedia) and
connect? If not, can you have user open a shell and type 'pulseaudio -C'

Yes it is. It started when I logged in this morning.

I don't see any Pulse Audio Manager in the Multimedia menu.
I tried to run pacmd and got these messages.
E: core-util.c: Failed to create secure directory: Permission denied
E: pacmd.c: No PulseAudio daemon running
The messages are the same and look related to lack of authorities to
access certain parts of the program.

SELinux is permissive and system has been retouched. There are no
SELinux warnings related to this.
Now, I have a local account for testing and was used for setting up the
system and I have sound in that account. There in only one log message
when I logged into that account.
Jan 8 11:01:40 eagle1 pulseaudio[16829]: module-alsa-sink.c: Increasing
wakeup watermark to 40.00 ms
And the KDE System Settings works as expected when trying to access Sound.
This points again to permission issues due to ldap account. I will
start looking at the various security settings when time permits later
today.
