    Server: Ubuntu 22.04.1 / NoMachine 8.11.3 free version
    Client: macOS 14.4 MacBook Pro M1 / 8.11.3 free version

    There are no audio pseudo-devices any more on the server. pactl list {sinks|sources} shows only Dummy Output and Monitor of Dummy Output respectively. Have tried puluseaudo -k, restarting the server, rebooting etc.

    At least the speaker forwarding was working properly before this last upgrade. Would downgrade if I could.

    Hi,

    Let me ask you a few questions in order to help me reproduce and investigate your issue.

    Which sound server do you use on your ubuntu? Ubuntu 22.04 should use PipeWire as default, but pulseaudio modules are also installed and you could switch to pulseaudio if you wanted to. You can check it by running ‘pactl info’. If “Server Name” simply says “pulseaudio” – you use pulseaudio. If “Server Name” is something like “PulseAudio (on PipeWire)” – then you use pipewire.

    Did you uninstall the old package and then install the new one? Or did you do the upgrade directly from the NoMachine application? If you did the latter, you can check if uninstalling and installing will help. Just download the DEB package you want and run:

    sudo dpkg -P <old_package_name> && sudo dpkg -i <new_package>.deb

    If you want to restart PipeWire server you should run:

    systemctl –user –now restart pipewire.{service,socket}

    You can also check audio configuration in /usr/NX/etc/node.cfg. The variable “AudioInterface” should be set to “pipewire” if you use pipewire or “pulseaudio” if you use pulseaudio.

    Regards,

    Kuba

    Sorry for the late response.

    > Which sound server do you use on your ubuntu? 

    From pactl info: Server Name: PulseAudio (on PipeWire 0.3.48)

    > Did you uninstall the old package and then install the new one?

    Earlier I had simply upgraded the server. Now I’ve uninstalled the old version and installed the new one from scratch.

    >  to restart PipeWire server you should run:

    Yes, I did that.

    > You can also check audio configuration in /usr/NX/etc/node.cfg.

    /usr/NX/etc/node.cfg has AudioInterface pipewire

    I switched to pulseaudio in node.cfg hoping for better results, but no joy. Restarted nxserver, then also  rebooted.

    Now I have a proliferation of NoMachine Output – 4 at last count – Output Device-s but none activates the speakers. Similarly there are a bunch of remapped nx_voice_out Input Device-s but none of them connect to the microphone.

    pactl list sources|sinks shows everything to be in SUSPENDED state.

    At this point I’ll settle for the speakers working.

    The speakers started working. Possible reasons:

    • updated the MacBook to macOS Sonoma 14.4.1 (23E224)
    • Removed wireplumber from the Ubuntu box

    The microphone picks up the speakers so it’s basically feedback and not usable.

    We were able to reproduce similar behaviour and have since opened a Trouble Report. The fix for this issue can be tracked using this link: https://www.nomachine.com/TR03V11111

    It will be in the next maintenance release.

    Please update to 8.12 which includes a fix for the TR I linked above.
