[X2Go-User] Redirect only specific sound devices?

[Buddy Butterfly]

Hi Mike,

sorted it out. So, if someone is interested, here is how to do
it. I tested it on Kubuntu 12.10.

On Ubuntu, pulse is in session mode by default. This means, it
obviously starts an instance per session. This is why I could
not see any devices when unsetting PULSE_CLIENTCONFIG. So,
to make it work, pulse has to be started system wide at boot.
Background on how to do it:

http://rudd-o.com/linux-and-free-software/how-to-make-pulseaudio-run-once-at-boot-for-all-your-users

What I did:

1. In /etc/init/pulseaudio.conf
   activate the line

	start on runlevel [2345]"

   which is commented out by default.

2. In /etc/pulse/client.conf set

	default-server = /var/run/pulse/native
	autospawn = no

3. Place the users that should have sound into group "pulse-access".

4. Reboot.

Only drawback is that KDE does not show the devices in system settings
anymore when natively using the system. But sound in KDE is working
perfekt. Devices can be seen with KMIX and outputs can also be
redirected (select output streams, right click on the currently playing
stream and choose move to....).

When you now connect via x2go everything is fine and the sound
gets redirected to the local system. But you can now start voip and
other programs to use the local sound devices with unsetting
$PULSE_CLIENTCONFIG beforehand. Example running in konsole:

unset PULSE_CLIENTCONFIG
jitsi

Runs jitis with the local sound devices. It can be configured to use
usb sound card of a headset directly, etc.

Cheers,
Matt
