I've implemented a set of 6 scripts to install Guacamole w/NGINX, Tomcat8, Mysql on Ubuntu 16.04 servers.
I also install Pulseaudio in the Host/Server and configure it (/etc/pulse/
default.pa) to load the Pulseaudio TCP module:
load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;10.0.3.0/24
auth-anonymous=1
On a server I also create multiple LXD containers each also running Ubuntu
16.04 (although they could be centos, debian, opensuse, fedora etc).
In each LXD container I install ubuntu-mate Desktop Environment and both
xrdp & x11rdp which I compiled to include pulseaudio 8 support since that's
what Ubuntu 16.04 uses.
I also add a statement to /etc/bash.bashrc
export PULSE_SERVER=10.0.3.1:4713
so that each User Account created in the Container inherits that
Environment variable which makes the Host/Server's Pulseaudio Server
available to the users of the LXD containers.
In Guacamole Web Proxy I create connections to each of the LXD containers
which all have 10.x.x.x network addresses and can access the Host/Server
via a 10.x.x.x bridge.
Each connection is configured with RDP and RDP security.
I create several test users also and give each use access to multiple LXD
container connections.
Logout of Guacamole & log back in as one of the "test" users and I can
connect to and log into Ubuntu-Mate desktop on any of the containers just
fine.
Running "pactl list modules" in any of the LXD containers shows the same
Pulseaudo "modules" loaded as the Host/Server.
However, audio/sound played in any of the LXD containers can't be heard.
example:
executing "aplay /usr/share/sounds/alsa/Front_Center.wav" in an LXD
container does show the .wav file playing but there is no sound heard via
my remote web browser.
Now my Question is this...
I *can* connect to the Host/Server's Guacamole Web Proxy via my HTML5 web
browser.
I select an RDP connection to one of the LXD container Desktops and *DO
connect* with the xrdp/x11rdp running in that Container *and DO* get the
Ubuntu-Mate desktop presented to me.
Audio/Sound *does appear* to "play" from that desktop but somewhere/somehow *it
is not picked up by my Guacamole HTML5 connection.*
How does Guacamole normally make the connection for audio in order to play
it back to the remote user over the HTML5 Browser?
I'm at a loss where between guacamole, pulseaudio, xrdp the audio
connection is not right?
Thanks for any insights.
FYI.. I am usually testing the scripts on either AWS or Digital Ocean cloud
servers.
Not sure if attachments work with this Mailer list but I'll add a picture
of what I'm doing anyway in case it does and it can help visualize what I
described.
