xrdp audio redirection instructions issue

[z9tree]

I just got the xrdp audio redirection sink working with the instructions listed here:

https://github.com/neutrinolabs/pulseaudio-module-xrdp/wiki/README

However, following the directions exactly as written did not work. The module that got built following the directions exactly on a fresh centos 7.5 install (after updating all packages) resulted in an audio sink that showed up in the system properties. However, if a bell sound tried to be played from the terminal or testing audio at all, no audio would come through and the entire desktop environment would lock up for about a minute. If multiple bells tried to be sounded from a terminal it would lock up and queue them all it seemed - I got some faint bell sound but after a long delay for each one. So, I removed the .so files from the pulseaudio modules folder.

The instructions should be amended as follows, as this is the procedure that I used to get it to work:

At the step after you clone the repo by default you are on the devel branch, so first checkout master:

git checkout master

Then during the configure stage this will now fail because using only the packages described it did not have the xrdp headers, so:

sudo yum install xrdp-devel

Then the rest of the instructions with running the bootstrap script, configuring, making, and installing worked and resulted in a working audio redirection setup.

Thank you! I had the same lock up problems on Debian Stretch, checkout master solved it.

I have similar problems on Ubuntu 18.04.2 LTS.

My issue starts at instruction step "Finally, let's build xrdp source / sink modules. You'll have two .so files module-xrdp-sink.so and module-xrdp-source.so":

In line 3 when it tells me to input following code: ./bootstrap && ./configure PULSE_DIR=/path/to/pulseaudio-11.1 (in my case /path/to/pulseaudio-11.1 equals /tmp/pulseaudio-11.1) i get following output:

configure: error: Package requirements (libpulse) were not met:

No package 'libpulse' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBPULSE_CFLAGS
and LIBPULSE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more `details.

And if i type make after that i get following output: make: *** No targets specified and no makefile found. Stop.

When you have the package installed and get this type of error it usually means that you are missing a -dev package, you can find the right one by looking at packages.ubuntu.com and search package content for libpulse.pc in this case it returns a libpulse-dev package.
