    Hi,

    You are using Windows OS on the server machine, right?

    In this case, when you connect to the server, NoMachine will check what the default audio output device is and will transmit audio stream from this device to the other side.

    If you want to change this default device used by NoMachine, you have to do this in Windows sound settings, then close the NoMachine session and connect again.

    There is no option for now to choose it in NoMachine application when the session is running.

    Hi,

    We have checked your environment but we did not notice any problem like that using Ableton Live.

    NoMachine audio devices should be only used on the server side so on the client side your default audio output device should be set to headphones, speakers etc.

    On the server side NoMachine application will take default output device and read audio stream from this
    device (to transmit it to the other side). If you want to change default output device, you have to close the session
    and connect again via NoMachine.

    If you are able to hear audio from other application than NoMachine on the client
    side, I suggest to focus on the remote machine.

    1. What version of Ableton Live do you use?

    2. Does audio work always correctly when you are not running Ableton Live?

    3. What is your default sound output device? Can you please attach screenshot
    of Playback tab in Sound panel? Go to Control Panel -> Hardware and Sound -> Sound.

    4. Please check also if your default sound output device is running in the exclusive mode
    and try to disable it.

    Hi,

    NoMachine on the client side on the Linux system is not creating any source or sink so because of that
    you will get no result from these commands. NoMachine application should use default sound output (headphones, speakers etc.). If you are able to hear some audio from other applications I will suggest to leave it for now and focus on MacOS.

    1. Do you use NoMachine 6.10.12 on this mac 10.15?

    2. When you connect to the mac 10.15 for the first time via NoMachine
    you should get request which reports that “NoMachine” would like to
    access the microphone. Did you get it?

    3. Please can you open Settings -> Security & Privacy -> Privacy -> Microphone panel and check if
    “NoMachine” is available there (like on the attached screenshot)?

    Hi,

    The audio quality slider is related to the Opus sample rate, frame size, channels etc. All these things affect how fast the audio stream can be processed and transmitted to the other side. We are using variable bitrate encoding
    which means that bitrate can be changed depending on the audio stream to achieve more consistent quality.

    1. The lowest point (the best performance):
    Opus sample rate: 12000 Hz
    Number of channels: 1

    2. Middle position (compromise between performance and quality)
    Opus sample rate: 24000 Hz
    Number of channels: 2

    3. The highest point (the best quality)
    Opus sample rate: 48000 Hz
    Number of channels: 2

    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
