We are using xrdp 0.6 with x11rdp.

This is far from what I have seen so far. I need to retest on a decent PC with
Gb Ethernet... or understand what else this depends on.

Sound is not a problem on a LAN .
Jay Sorg just replied that sound redirection will be available on 0.7, which is
great news. That will enable sound even on access from different networks.
Meanwhile, if you're on a LAN, you can run this on the login script (ex:
startkde) on the XRDP server:
--------------------------
XRDPLOG=/var/log/xrdp/sesman.log
TERMINALIP=`grep $USER $XRDPLOG |tail -n 1 | awk '{ print $12 }' | awk -F: '{
print $1 }'`
export PULSE_SERVER=tcp:$TERMINALIP:4713
--------------------------
On the client you must configure pulse audio to accept this connection. The .pa
file can have something like:
--------------------------
#!/usr/bin/pulseaudio -nF
# accept network sound - http://www.pulseaudio.org/wiki/NetworkSetup
load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.0.0/16
load-module module-alsa-sink sink_name=alsaoutput device=hw:0 rate=48000
channels=6
set-default-sink alsaoutput
# and now, the usual stuff, based on Ubuntu gutsy /etc/pulse/default.pa...
# Various ways to deliver sound to this server
load-module module-esound-protocol-unix
load-module module-native-protocol-unix
# Automatically restore the volume of playback streams
load-module module-stream-restore
# Automatically move streams to the default sink if the sink they are
# connected to dies, similar for sources
load-module module-rescue-streams
### If autoexit on idle is enabled we want to make sure we only quit
### when no local session needs us anymore.
load-module module-console-kit
.nofail
# Publish connection data in the X11 root window
load-module module-x11-publish
--------------------------
