Hi,
Unfortunately updating to latest NoMachine break sound streaming to client.
The setup I’m using on Slackware 15.0 and -current (15.1) is described in this thread https://forum.nomachine.com/topic/message-cannot-find-the-default-environment-please-contact-your-system-administrator-on-latest-slackware
Previous update works fine.
I don’t have particular error in system log and I’ve tested combinations of autospawn and DefaultDesktopCommand with no luck.
I only have <nomachine_8.4.2_1_x86_64.tar.gz> available on local drive, so I rolled back this old working version. If you can provide a link to previous version it is more than welcome.
I have Slackware 15.0 and Current (15.1) with KDE available to cross check.
Help appreciated.
Best,
We’ve tested with the latest 8.5 and the latest Slackware and don’t have issues with sound.
Are you using Pipewire? Is the Slackware machine headless?
Please tell us the output of
sudo grep Audio /usr/NX/etc/node.cfg.I take it that you are using the Free Edition?
Hi,
Nothing significant in audio forwarding has changed in the last update. Have you updated pipewire recently? There is a chance they changed something that broke sound streaming in your case. You can check logs on the server side under these paths: ~/.nx/node/C-<display>-<session-ID> to see whether you have any warnings or errors related to audio.
Regards,
Kuba
Ok I finally manage to find an error message, thanks Kuba to pointing me to the right folder 😉
With 8.5.3 i have this error message that i don’t have with 8.4.2, in:
/home/<user>/.nx/M-<hostname>.<domain>-13001-EBB6855A33251194194DDE1C8CB092AB/session
/usr/bin/pulseaudio: symbol lookup error: /usr/lib64/pulseaudio/libpulsecore-15.0.so: undefined symbol: XSetIOErrorExitHandler
Message is repeated when user connect with or without the autospawn modification in /etc/pulse/client.conf.
Btw I did not do any modification to node.cfg or server.cfg after install, only “autospawn = no” to have sound on client.

Hi Britgirl, Kuba,
Thanks for feedbacks,
I’m using NoMachine free edition, I’m not using Pipewire and server have a monitor. I’m running KDE and computer start it automatically (runlevel 4)
Slackware is 15.0 with latest updates (including Kernel 5.15.94) and few softwares installed.
NoMachine install:
1) Extract the archive in the /usr/NX directory:
# tar -C /usr/ -xzf nomachine_8.5.3.tar.gz
2) Run the installation script by specifying a different Linux distribution, for example:
# /usr/NX/nxserver –install slackware
Then, in order to make NoMachine server and services starting automatically after a reboot, do the following:
3) Copy the NoMachine init script to the proper place:
# cp /usr/NX/scripts/init/nxserver /etc/rc.d/rc.nxserver
# chmod +x /etc/rc.d/rc.nxserver
4) Edit /usr/NX/etc/node.cfg:
# DefaultDesktopCommand “env -u WAYLAND_DISPLAY /usr/bin/dbus-launch –sh-syntax –exit-with-session /usr/bin/startplasma-x11”
# Works fine in runlevel 3 with sound (SDDM/KDE not started):
# Works fine in runlevel 4 (SDDM/KDE started) with “autospawn = no” in /etc/pulse/client.conf for sound:
# runlevel configured in /etc/inittab
DefaultDesktopCommand “/usr/bin/env XDG_CONFIG_DIRS=/etc/xdg:/etc/kde/xdg /usr/bin/dbus-launch –sh-syntax –exit-with-session /usr/bin/startplasma-x11”
5) Edit /etc/pulse/client.conf
autospawn = no
My today test: I open Chrome and put Youtube radio, sound output to my headset, I use another computer connect to desktop with an other public IP address or from local network address, sound switch to NOMACHINE when the client connect.
Works fine with with 8.4.2 (i had no issue with the version before 8.5.3, i don’t remember the exact version I was on but i do update every time a new version is available):
~$ grep Audio /usr/NX/etc/node.cfg
AudioInterface pulseaudio
#EnableAudio 1
# Specify path and name of the command to start PulseAudio server.
CommandStartPulseAudio “/usr/bin/pulseaudio –high-priority=no”
DefaultDesktopCommand “/usr/bin/env XDG_CONFIG_DIRS=/etc/xdg:/etc/kde/xdg /usr/bin/dbus-launch –sh-syntax –exit-with-session /usr/bin/startplasma-x11”
Client is connected to desktop:
~$ pactl list sources | grep NoMachine
Description: Monitor of NoMachine Output
device.description = “Monitor of NoMachine Output”
Description: Remapped Monitor of NoMachine Output
device.description = “Remapped Monitor of NoMachine Output”
~$ pactl list sources | grep nx
Name: nx_voice_out.monitor
Monitor of Sink: nx_voice_out
Name: nx_remapped_out
device.master_device = “nx_voice_out.monitor”
Doesn’t work with 8.5.3, no sound on client computer. (I did a server reboot just in case after installing 8.5.3)
~$ grep Audio /usr/NX/etc/node.cfg
AudioInterface pulseaudio
#EnableAudio 1
# Specify path and name of the command to start PulseAudio server.
CommandStartPulseAudio “/usr/bin/pulseaudio –high-priority=no”
DefaultDesktopCommand “/usr/bin/env XDG_CONFIG_DIRS=/etc/xdg:/etc/kde/xdg /usr/bin/dbus-launch –sh-syntax –exit-with-session /usr/bin/startplasma-x11”
Client is connected to desktop:
~$ pactl list sources | grep NoMachine
Description: Monitor of NoMachine Output
device.description = “Monitor of NoMachine Output”
Description: Remapped Monitor of NoMachine Output
device.description = “Remapped Monitor of NoMachine Output”
~$ pactl list sources | grep nx
Name: nx_voice_out.monitor
Monitor of Sink: nx_voice_out
Name: nx_remapped_out
device.master_device = “nx_voice_out.monitor”
Everything look exactly the same to me, nothing in syslog or any system log that i can see, as soon as i switch back to 8.4.2 it works.
Hi,
It seems you have a pulseaudio internal issue. Have you tried reinstalling or update pulseaudio to v.16?
Don’t look at NoMachine Output, it’s used for microphone forwarding. For audio forwarding we just capture data from the default sink and send it to the client side.
Regards,
Kuba
Hi Kuba,
I have another computer running Slackware current (15.1) and experiencing the same issue with 8.5.3:
~$ pulseaudio --version
pulseaudio 16.1Any advice on where to start to troubleshoot this on my side are welcome.
I will also ask on the Slackware forum.
Best,

I can reproduce the issue on three computers running current 15.1 and Slackware 15.0. Two of them have been fully re installed in the last month, interesting that you can’t reproduce, I don’t see what I can do that can cause this.
Having some spare time tonight, I did a fresh Slackware 15.0 install on a spare drive, no package update, just edited /etc/pulse/client.conf (autospawn = no) and installed 8.5.3
8.5.3 doesn’t stream sound to client
8.4.2. works fine
Best,
Can confirm on 8.5.3 NoMachine with audio from PulseAudio, no sounds go into client machine. Downgrading back to 8.4.2 makes the audio work again. Please fix on the next updates, thank you.
Host: Manjaro Linux
Clients used: Windows 11 and Android phoneEveryone,
here is the Trouble Report:
Audio is not available in the session with NoMachine server v.8.5.3 on Manjaro Linux and other distros
https://kb.nomachine.com/TR05U10867its fix will be in the upcoming 8.6.
