version: 1.1.0.2

Hi,

when starting x2goclient in thinclient mode, pulseaudio gets started
in the background. This blocks remote audio when using the
RDP-DirectConnect feature of x2goclient.

When you do this:

/etc/init.d/x2gothinclient stop
X &
export DISPLAY=:0
ln -s /etc/x2go/x2gothinclient_sessions ~/.x2goclient/sessions
x2goclient --thinclient

sound in an RDP-DirectConnect session works.
So the Pulseaudio start takes place somewhere else - x2gothinclientd
maybe? - and needs to be stopped for RDP-DirectConnect, as it blocks
the audio device.

How that can be accomplished, without killing sound support for
regular X2Go sessions, I don't know.

Who was the one that originally asked for the RDP-DirectConnect
feature?  How do they handle sound, or do they not need it?

- -Stefan

Additional info:

Sound via RDP works when:

a) Pulseaudio is not running

*and*

b.1) rdesktop is called with:
     -r sound:local -f -u DOMAIN\\User -p Password Server:3389

*or*

b.2) xfreerdp is called with:
     --ignore-certificate --plugin rdpsnd -d DOMAIN -f -u User \
     -p Password Server:3389

It doesn't matter if b.1) or b.2) is used on the command line with X
and export DISPLAY=:0, or through an x2goclient with the corresponding
session parameters.

Hi Stefan,

yes pulseaudio is started from x2gothinclientd - rdesktop does not
support pulseaudio as audio backend - but you can workaround that with
'padsp' from the pulseaudio-utils package. - you just have to prefix the
rdesktop command with padsp like:

padsp rdesktop -u <username> -f -r sound:local <address>

then pulseaudio redirects the access to /dev/dsp of rdesktop to itself.

xfreerdp should have native pulseaudio-support so it depends on your
choice of software. To force xfreerdp to use pulseaudio you could add
the parameter '--data tsmf:audio:pulse' to the xfreerdp-command

I know of padsp, but it seems there is no way I can just add this call
somewhere in the config.  This looks like it has to be added to
x2goclient's source.

(I can only add additional parameters after the rdesktop/xfreerdp
call, but nothing in front of it.)

So,
--ignore-certificate --plugin rdpsnd --data tsmf:audio:pulse -d DOMAIN
-f -u User -p Password Server:3389
doesn't work, it throws me right back at the login prompt.

Running it on the command line

xfreerdp --ignore-certificate --plugin rdpsnd -d DOMAIN -f -u User -p
Password Server:3389

(i.e. *without* the parameter you suggested) returns, when pulseaudio
is loaded:

loading plugin rdpsnd
Warning xf_GetWindowProperty (140): Property 484 does not exist
connected to Server:3389
freerdp_load_library_symbol: failed to open
/usr/lib/i386-linux-gnu/freerdp/rdpsnd_pulse.so:
/usr/lib/i386-linux-gnu/freerdp/rdpsnd_pulse.so: cannot open shared
object file: No such file or directory
freerdp_load_plugin: failed to load rdpsnd_pulse/FreeRDPRdpsndDeviceEntry

So it does try to do some pulseaudio'ish things, but fails.  Thus, I'm
guessing xfreerdp in Debian Wheezy is too old/doesn't include
Pulseaudio support for some reason.

Also, note that adding the parameter you suggested doesn't work out of
the box - e.g. when called like this:

xfreerdp --ignore-certificate --plugin rdpsnd -d DOMAIN -f -u User -p
Password --data tsmf:audio:pulse Server:3389

it dies instantly with:

loading plugin rdpsnd
invalid option: --data
failed to parse arguments.

so the position of the parameter seems to matter.

Additional info: xfreerdp --version returns "This is FreeRDP version
1.0.1"

Hi Stefan,

i don't know about the 'rdpsnd'-plugin for xfreerdp - the official
documentation suggests 'drdynvc':

Never made it back to wheezy, though.

Jessie has it:
https://packages.debian.org/jessie/amd64/libfreerdp-plugins-standard/filelist

And should also support the --data tsmf:audio:pulse parameter.

Yeah... Compiling freerdp against pulseaudio cannot be fixed in wheezy  
anymorere due to Debian policy (note, that I am the current freerdp  
maintainer in Debian).

But you could rebuild freerdp on wheezy and enable pulseaudio support,  
I guess.
