Hi,

Are you trying to set up PulseAudio via root?

By default PulseAudio is not intended to be run as root but you can try to use it in a system-wide mode.

Edit the following variables in /etc/pulse/daemon.conf:

– change daemonize = no to daemonize = yes

– change system-instance = no to system-instance = yes

Remember to remove ‘#’ or ‘;’ sign to uncomment line.

After that reboot system and try to access pavucontrol.

Please note that in some cases running PulseAudio in system-wide mode is not recommended.

More information you can find here:

Hi,

We will need logs to investigate the problem.

1. Please collect NoMachine logs from this macOS 10.13. How to do this you can find here:

https://www.nomachine.com/DT10O00163

2. After that run the following command to gather system logs:

cat /var/log/system.log | grep -e nxnode -e nxau >> nxsystem.log

Please send NoMachine logs and nxsystem.log file to forum[at]nomachine[dot]com using the title of
that forum’s thread as the mail’s subject.

Hi,

Sorry for the late response. Yes, the problem is related to the Windows system.

when I open the sound settings in the control panel, the system shows a blue screen.

Did you see what caused this BSOD? Could you send us mini dump file generated by the operating system? You can find it in %SystemRoot%\minidump directory (by default it should be C:\Windows\minidump). Please send it to forum[at]nomachine[dot]com using the title of that forum’s thread as the mail’s subject.

1. As a sound output, “NoMachine microphone adapter” is selected by default. Like the sound input is the same.

“NoMachine microphone adapter” should not be set as a default output device when you want to use microphone.

<cite>5. First I left it as it was, then I tried to activate other sound outputs. It had no effect.</cite>

Did you try to do this before you connect with NoMachine? If not, please set the default output device to something different than “NoMachine microphone adapter” and then connect to the server via NoMachine. Leave default input device  as it is (“NoMachine microphone adapter”).

Sorry for the late response. We were trying to reproduce this problem but we could not.

I need to ask more questions to investigate the problem.
Before that, please restart the PulseAudio server on Kubuntu machine using the command bellow:

pulseaudio -k; pulseaudio -D; sudo /etc/NX/nxserver --restart

1. When you are connected to the host via NoMachine, what is the default sink and source on the server? You can check this with the following command:

pactl info | grep Default

2. From the provided list I can see that all nx sinks are created properly but “Simultaneous output to NoMachine Output” is not in the “RUNNING” state. It should be set to the default sink by the NoMachine and because of that, applications like Firefox should play on this sink. You can check if applications are using correct default sink in the “Playback” tab of pavucontrol.

Also debug logs will be helpful in this case. How to do it you can find here:

https://www.nomachine.com/DT10O00163#1.1

and please send the logs archive to forum[at]nomachine[dot]com.

Hi,

We need to ask you some questions to investigate the problem.

1. What is your default input/output device on the Windows system?

2. What do your Skype audio settings look like?

3. Do you use Skype as a desktop application or do you use it via Chrome for example?

4. This Skype application is already running before you connect with NoMachine?

5. Have you changed any audio settings on Windows or did you just leave it as it is by default?

Hi,

Can you please check the following things on the server side while using NoMachine and playing something?

1. Run the following command in the terminal and paste or attach the output in your reply:

pactl list sinks

2. In “Recording” tab of pavucontrol you can see that NoMachine application is recording audio from some source. What is the name of this source?

3. You can also look into pulseaudio logs and check if there are some error/warning logs. By default you can find them in “/var/log/syslog”. Please run the following command in the terminal and attach the file “pulseaudio.log” in your reply.

cat /var/log/syslog* | grep -i pulse > /tmp/pulseaudio.log
