CentOS - Jul 2014 - How to enable sound for other users but the one who owns the current session

Hello there!


I'm trying to get sound from applications running from other users bug
the one who owns the current GNOME sessions.

Typically, my default user is "A" and he's running the GNOME
session,
logged in graphically. From this session, I open terminals, su to other
users (B or C, non-root) and run mplayer or firefox. No sound for these.

Adding those users to the "audio" group didn't help. Any idea how
to do
this?


Regards,

That is pulse problem, daemon is started with first user as owner. I do
not know workaround or fix.

some google-fu suggests group 'pulse-access' should be used.   no idea 
if thats actually legit.

with some semblance of reliability once long ago I can tell you that it
involves something around:
load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1

This implies the pulse server must provide a local network service and
the clients must be configured to connect to this server.

Updating default.pa in .pulse directories and granting access to pulse*
groups also rings a bell.
Sadly I kept few notes on this so can only find this hint at present.
There must be better ways to do it and if you get it working I would be
keen to know how, so please provide feedback.
I also recall murmurs of security issues around shared pulse services,
obviously more so if the ip is not localhost, so consider that too.

If A enables sound, does it work for other users?
