focal fossa ubuntu not work with xrdp

[tst32]

Hello!
after git clone --depth=1 https://github.com/neutrinolabs/pulseaudio-module-xrdp
i built successfully as by wiki.

ls $(pkg-config --variable=modlibexecdir libpulse) | grep xrdp
module-xrdp-sink.la
module-xrdp-sink.so
module-xrdp-source.la
module-xrdp-source.so

and no sound in xrdp session
in xrdp.in sound = true
what do have i do?

[matt335672]

Run the load_pa_modules.sh by hand to see if you're getting any errors.

See also #79 and #82 which might be relevant.

[tst32]

Thanks for your prompt response.
it seems to me that my problem is related to #79 and #82 (permissions) too.

./pulseaudio-module-xrdp/instfiles/load_pa_modules.sh 
Failed to initialize module
? Can't load pulseaudio xrdp-sink
Failed to initialize the module
? Can't load pulseaudio xrdp-source

the output is slightly different further

pulseaudio --start do not fix sound problem, but new devices appear

devices disappear after shell close

then

do i need to purge pulseaudio-xrdp and then reinstall after repo clone/build with
sudo make install MKDIR_P="mkdir -p -m 0755" INSTALL_SCRIPT="/usr/bin/install -m 0755" ?
or something else?

[matt335672]

Try running bash -x /usr/libexec/pulseaudio-module-xrdp/load_pa_modules.sh rather than bash -x ./pulseaudio-module-xrdp/instfiles/pulseaudio-xrdp.desktop. As you've already seen, the second one of these isn't a script.

Also, what do you get for:-

ls -l $(pkg-config --variable=modlibexecdir libpulse) | grep xrdp

[tst32]

ls -l $(pkg-config --variable=modlibexecdir libpulse) | grep xrdp

[matt335672]

That's useful - it doesn't look like a permissions problem.

In one terminal, can you type the following to get a log from the pulseaudio daemon:-

pacmd set-log-level 3
pacmd set-log-target newfile:/tmp/pa.log
tail -f /tmp/pa.log

Then in another terminal, run /usr/libexec/pulseaudio-module-xrdp/load_pa_modules.sh and see what we get in the log.

[tst32]

tail -f /tmp/pa.log

What could it mean, versions diffs?

[matt335672]

It looks like you've built the module on a different Ubuntu version, or against the wrong pulseaudio sources.

How did you build it exactly?

[tst32]

git clone --dept=1 https://github.com/neutrinolabs/pulseaudio-module-xrdp.git
then followed readme. a few days ago.
I don't know about the parallel installed version. Is there anything i can learn more about it, or is there some way to remove it?

[matt335672]

The readme points to the wiki here:-

https://github.com/neutrinolabs/pulseaudio-module-xrdp/wiki/Build-on-Debian-or-Ubuntu

Did you use scripts/install_pulseaudio_sources_apt_wrapper.sh ?

If not, try using that.

[tst32]

Yes,after delete do scripts/install_pulseaudio_sources_apt_wrapper.sh
rm -rf /home/userme/pulseaudio /home/userme/pulseaudio.src/ /home/userme/pulseaudio-module-xrdp ;
got

** Current distro 'focal' does not appear to be supported by debootstrap
   Need --suite switch?

--suite=focal
** Unsupported suite 'focal'
lsb_release -a

No LSB modules are available.
Distributor ID:	Ubuntu

[tst32]

is it good idea to do-release-upgrade?

[matt335672]

I've just had a look at this on my machine running 'jammy', and I'm getting the same:-

 scripts/install_pulseaudio_sources_apt_wrapper.sh 
** Current distro 'jammy' does not appear to be supported by debootstrap
   Need --suite switch?

I've traced it back to a change in the debootstrap command, and the way it handles getting information about available distros.

I've attached a patch file patch.txt. Can you download it as /tmp/patch.txt and enter this command from within the pulseaudio-module-xrdp directory:-

patch -p1 </tmp/patch.txt

You should get the message patching file scripts/install_pulseaudio_sources_apt_wrapper.sh. Then try running the script again.

patch.txt

[tst32]

thanks for your efforts, i have patched install script after all new git clone
git clone -b devel https://github.com/neutrinolabs/pulseaudio-module-xrdp.git
complete cd ~/pulseaudio-module-xrdp/scripts ./install_pulseaudio_sources_apt_wrapper.sh --suite=focal

my actual focal ubuntu was upgraded from bionic, and i think that old pulseaudio is error cause. i'm a bit frustrated, do i need to remove pulseaudio completeley, then reinstall to v13.99 ?

[matt335672]

There shouldn't be any of the old pulseaudio left.

Remove the pulseaudio modules completely with:-

MODDIR=$(pkg-config --variable=modlibexecdir libpulse)
ls -l $MODDIR/module-xrdp-*
sudo rm $MODDIR/module-xrdp-*
ls -l $MODDIR/module-xrdp-*

Then redo the sudo make install, check the modules are back and try again.

[MrZajic]

I have the same problem. Stucked on /usr/libexec/pulseaudio-module-xrdp$ ./load_pa_modules.sh:
