Changes:
 x2gothinclient (1.5.0.0-0x2go1) RELEASED; urgency=low
 .
   [ Mike Gabriel ]
   * New upstream release (1.5.0.0):
     - Stop advertising GNOME in default session profile. Switching to MATE.
     - Use type=auto for automatic keyboard detection as default in example
       session profiles.
     - Avoid error message in x2gothinclient_shell if the chroot does not have
       a file-or-symlink /etc/resolv.conf.
     - Use resolv.conf file from host system when running x2gothinclient_upgrade.
     - Add COPYING file.
     - Run x2gothinclient_shell and x2gothinclient_upgrade with LANG=C.
     - Don't run x2gothinclient_init inside TCE chroot operations
       (x2gothinclient_shell or x2gothinclient_upgrade).
     - Avoid x2gothinclient_init failures, use if..then..fi instead of
       the test command.
     - Init scripts: Provide status option.
     - Use lazy unmounts for unmounting bind-mounted /proc, /sys, /dev/pts
       after exiting the TCE chroot (x2gothinclient_create, x2gothinclient_shell,
       x2gothinclient_upgrade, x2gothinclient_cleanup).
     - Assure that a tmpfs under <chroot>/root gets mounted and cleanly
       unmounted (x2gothinclient_shell, x2gothinclient_upgrade).
     - Use run-parts to initialize the TCE during runtime. (Fixes: #419).
     - New TCE component: x2gothinclient-minidesktop. Instead of using
       X2Go Client as login manager, we launch a minimal MATE desktop and
       connect to X2Go sessions from there.
       . Add WindowList applet to MATE panel.
       . On $HOME creation, copy x2gothinclient-minidesktop.desktop into
         ~/Desktop.
       . Provide init script for x2gothinclient-minidesktop to handle maintenance
         tasks if TCE is installed with in minidesktop flavour.
       . Tweak MATE minidesktop via GScheme overrides.
       . Launch MATE minidesktop via LightDM autologin feature.
       . Add XDG autostart .desktop file for the TCE's X2Go Client.
       . Add VERSION.<package> file for x2gothinclient-minidesktop.
       . Make X2Go TCE layout / appearance overridable by installing
         debian-edu-artwork package.
       . Use default X2Go Client background for x2gothinclient-minidesktop.
         Provide configurable desktop background instead. Install desktop
         background as desktop-base alternative.
       . On minidesktop TCE creation based on wheezy, pull in packages from
         wheezy-backports (i.e. MATE desktop environment).
       . MATE Application menu: Move the default X2Go Client .desktop file out
         of the way (dpkg-divert) and provide the TCE's .desktop file instead.
       . Make sure that launching x2goclient via a terminal or the run command
         box in MATE results in the restricted TCE X2Go Client.
       . Make contrib and non-free software available on minidesktop TCE
         creation.
       . Disallow Caja to handle storage media (automounting, opening, etc.).
       . Enable usbmounts and smartcard rules for minidestop TCE flavour.
       . Enforce TCE session restart after logout.
       . Provide Web browser shortcut in the MATE panel.
       . Enable native-protocol-tcp module in pulseaudio on every X2Go Client
         launch. Allow access from local host only, require auth cookie.
     - Adapt management package to TCE flavouring. Add new configuration
       option in x2gothinclient_settings: TC_FLAVOUR (can be: minidesktop or
       displaymanager).
     - Use proper quotations in several X2Go TCE scripts.
     - Don't choke if /etc/resolv.conf in the TCE chroot is a symbolic link
       (in x2gothinclient_shell, x2gothinclient_upgrade).
     - README.i18n: Add file that explains the translation workflow for
       this package. Thanks to Mark Pedersen-Cook for drafting this file.
     - For X2Go TCE in display manager mode, set login backgrounds of all
       screens (if more than one is used) to a blue'ish background color.
       (Fixes: #718).
     - TCE in display manager mode: Don't align multiple heads next to
       one another if a (Wacom) touchscreen is detected in the list of heads.
       (Fixes: #719).
     - management/sbin/x2gothinclient_update: Create
       $TC_CHROOT/etc/x2go/x2gothinclient_init.d/ before copying files into it.
     - management/sbin/x2gothinclient_update: Consider known_hosts2 FreeRDP host
       key files, known_hosts was used for FreeRDP v1.x and are in fact
       deprecated nowadays.
     - management/sbin/x2gothinclient_create: Stop using deprecated --force-yes.
     - 010_x2gothinclient-fresh-home: Install FreeRDPv2's known_hosts2 file into
       ~x2gothinclient user's home dir when creating a fresh home.
     - x2gothinclient_sessions: Provide RDP-Direct session profile example that
       utilizes FreeRDPv2 rather than deprecated FreeRDPv1.x. (On Debian stretch,
       it is recommended to use FreeRDPv2 from Debian stretch-backports).
     - x2gothinclient-<TC-FLAVOUR>_start: Drop requirement of having symlink
       /etc/x2go/x2gothinclient_start. Now all code passages that use the _start
       wrapper, use the x2gothinclient-<TC-FLAVOUR>_start file directly.
   * debian/control:
     + Rename bin:package: x2gothinclient -> x2gothinclient-daemon.
     + Make sure x2gothinclient-minidesktop pulls in X11 and X2Go Client.
     + New bin:package: x2gothinclient-common. Commonly shared by
       x2gothinclient-minidesktop and x2gothinclient-displaymanager
     + Add D (displaymanager flavour, minidesktop flavour): pinentry-x2go.
     + Add D (x2gothinclient-minidesktop): lightdm.
     + Add R (x2gothinclient-minidesktop): flashplugin-nonfree.
     + Add R (x2gothinclient-chroot): ntp.
     + Move to Pre-D (x2gothinclient-minidesktop): x2goclient, lightdm. Make
       sure those packages are installed already avoiding dpkg-divert failures.
     + Allow co-installation of displaymanager and minidesktop bin:pkgs. They
       have no conflicting files and we should rather make the startup mode
       configurable through debconf.
   * debian/copyright:
     + Use copyright-format 1.0.
 .

Subject: Problem running audio applications in TCE mode

Date: Fri, 23 Sep 2016 16:25:46 +0200 (CEST)

Package: x2goclient
Version: 4.0.5.3
Severity: Critical

I managed to fix about every bits here and there but there is still one important part that I can't get to fix which is managing audio applications to work in TCE mode.

To be clear, what I call "TCE mode" is pxe booting an diskless station with x2gothinclient (per the doc setup with default settings, Debian wheezy based with heuler x2go client)

When I open a X2Go session with a local x2go client on my Ubuntu laptop (or even with x2goclient under windows), no problem, I have sound with PulseAudio fully working, I can play videos on youtube, hear MP3s with totem or any other audio application.
Running the same session with a TCE client works great until I want to hear a sound ... youtube videos are hanging with no sound, playing MP3s don't even start.

Here is a snippet from /var/log/syslog taken from the TCE when opening a new X2Go session :
