No audio on Nomachine only in Manjaro

I have 3 PC with Manjaro 20.03 installed and none of them gets audio output from NoMachine. The 3 of are quite different as one is a workstation (ryzen 3950x, 32g, Dual Nvidia rtx2070 & 1660), one is a htpc (Intel i3-4330, 16g), and Asus laptop(Intel i5-10510, 32g, Nvidia mx210).
The sound doesn’t work from any NoMachine server (VM or physical) even between Manjaro servers.

Any idea?

can you provide

inxi -Fxza --no-host

Have you a dummy output and sometimes after restart you have audio , sometimes not?
Many have problems the last days with audio with pc’s with snd-hda_-intel !
Open /etc/modprobe.d/alsa-base.conf and add the following line at the end:

options snd-hda-intel dmic_detect=0


pulseaudio -k && sudo alsa force-reload

You will heard the sound.

I don’t have this file or it is empty.

inxi -Fxza --no-host

I’ve edited your inxi output for better readability :slight_smile:

You must create it
Then in terminal:systemctl --user restart pulseaudio

I apologized for my stupidity but, create what? How?
ok I’ve created the file and made the command in terminal but it doesn’t work and now I have no sound at all. I lost all my sounds devices.

Change content of /etc/modprobe.d/alsa-base.conf to:

options snd-hda-intel model=generic

In Your home directory : rename ./config/pulse in ./config/pulse.old

Reboot your computer and adjust your settings in pavucontrol

These settings makes my computer unresponsive and freeze as soon as I touch the sound icon.

I also have the same problem… Everything worked on an older version of the kernel, but not since the upgrade of August 5th.
Please tell me if you find a solution!
By the way, I also installed fedora 32 on a different partition and everything works perfectly out of the box.

You have 5 audio devices !! Manjaro seems to have problems with multiple audio devices.I think we’ve got to wait until there is an update from Manjaro for this sound bug.
Delete the .config/pulse/ folder again ; some people say to change content in alsa-base.conf to:
options snd-hda-intel model=auto . Then in terminal : systemctl --user restart pulseaudio

I don’t know if that will work.
If it doesn’ work always try to restart pulseaudio again; sometimes you have sound and sometimes you don’t. It seems there isn’t really a solution yet to have permanently sound

As I said I have 3 pc with Manjaro and nomachine installed. All with very different configuration and none of them have audio coming from nomachine. I also installed Manjaro at work and no sound from nomachine either. I previously had Kubuntu, Pop_os, Mint, OpenSuse and Fedora installed on the same machine and they were all working fine. I love Manjaro but Nomachine is essential for me for my work so if I can’t get the sound working or find a work around I’m afraid I will have to find another distro.

I know it’s been almost a year, but just in case anyone else stumbles upon the same(?) problem:


  1. No sound from Manjaro NX server
  2. When connected, $ pactl info | grep Default doesn’t list Default Source: nx_voice_out.monitor
  3. In journalctl you get errors like: Error opening PCM device front:0: Device or resource busy


  1. Edit /etc/pulse/client.conf:
    Uncomment and change line ; autospawn = yes to autospawn = no
  2. Reboot.
  3. Hope for the best. :stuck_out_tongue:
