I have two Ubuntu 18.04 GNOME machines running v 7.4.1-1.
There is no audio received by the remote machine (one sound card) from the server machine. The server machine has three sound cards.
If the remote machine logs into a Win 10 machine, there is audio received. This server has two sound cards.
In all three machines “stream audio” is checked.
Any help would be appreciated.

1. Have you checked that PulseAudio is working on the server machine?
(it is installed correctly, users have access to it and it is running, also do you have some modified configuration for it?)
2. Check if the following /usr/NX/etc/node.cfg keys are set like this:
AudioInterface pulseaudio CommandStartPulseAudio "/usr/bin/pulseaudio --high-priority=no"
3. When you connect to that Linux machine run this command:
pactl list > all_list1.log
4. When you connect and if you had checked “mute server audio” option when connecting to the machine, let’s uncheck it from context menu and run again:
pactl list > all_list2.log
5. You can find the instructions on how to collect server side logs here: https://knowledgebase.nomachine.com/DT11R00182
5. Upload all_list1.log, all_list2.log, server-side logs.May 13, 2021 at 08:16 #33421
Many thanks for the reply!
1- yes it is running, pactl list provides much information.
2-yes set as shown
3-do I run this command from remote or server?
4,5 -on hold pending #3

client side is from where you connect and server where you connect from client. We need server side info. Do I get it right that, when you connect from same client to Windows you get audio but not when you connect to Ubuntu?
Also can you confirm that pulseaudio path is /usr/bin/pulseaudio on your system (on server) too?May 14, 2021 at 08:59 #33435
Yes when I log into server I have no audio on the remote. Also the audio on the the server mutes.
yes I confirmed server pulseaudio is running, and the keys under task 2 are correct.
I have attached the files from the server as requested. However I was unable to unmute from the GUI, could not find that, I am using v7.4.1. So I unmuted via the volume control of the pc for all_list2. This setting did not give audio on either server or remote.
Another bit of information, I do not know if it is relevant: the server PC does not have speakers. Audio output is via the LINE-OUT. Under pavucontrol, output devices, built-in-analog stereo, speakers are shown as unavailable, line out is selected.
The PC is a Dell Optiplex 990 I bought used.

Also do test the server that you get audio there (plug in to the Line Out jack)?May 14, 2021 at 17:05 #33441
There is no all_list1.log, all_list2.log files.
For change muting open context menu, from upper right corner, choose Audio –> Change Settings –> uncheck “mute audio on the server”.May 14, 2021 at 18:45 #33452
well I sent them!
all_list1.log: Sorry, this file type is not permitted for security reasons.
all_list2.log: Sorry, this file type is not permitted for security reasons.
change permision from root,try again.May 14, 2021 at 21:19 #33456
“Also do test the server that you get audio there (plug in to the Line Out jack)?”
That is how the test was run.

Hi again, good to hear that it works and you get audio from it.
Can you upload all_list1.log, all_list2.log, it’s important to understand what’s happening.May 17, 2021 at 11:44 #33470
Hi again, sorry for the late reply. I just received the email for this comment.
On the forum there is no file format restriction, if they are big files can you compress them and try to upload them?
And if you still get upload error you can send them directly to forum[at]nomachine[dot]com making sure to reference the title of the topic as the subject.May 17, 2021 at 11:45 #33472May 17, 2021 at 13:41 #33479
Hi again, to get audio on a Linux machine we use PA’s some modules but according to the logs they are not loaded. Just to be sure, did you take it during NM session yes (it will show there only during session)?
I have to ask to upload logs again.
On the server machine, run:
sudo /etc/NX/nxserver --debug --enable all
Instruction is missing in this part, but for getting all the necessary logs it needs to restart the server:
sudo /etc/NX/nxserver --restart
Then connect using NM to that server and collect logs:
sudo /etc/NX/nxserver --debug --collect
Upload those logs and while you are connected to the host machine using NM run and copy their output too:
pactl list sinks short
pactl list sources short
