Unable to get audio working in Rocky Linux 9

[bryan3301]

I also trying to make sound work on Rocky Linux 9.3. I ran across this article:

Centos NoMachine server no sound

sudo /usr/NX/bin/nxnode --audiosetup /etc/pulse
sudo /etc/NX/nxserver --restart

After running the commands above, I do see the NoMachine Outputs and Inputs. So far; however, I still do not have audio coming though.

Here is the full process I used to get NoMachine working on Rocky Linux 9.3.

Download NoMachine

Install NoMachine via local RPM

sudo rpm -i nomachine_8.10.1_1_x86_64.rpm

Create firewall service entry

sudo cat << EOF > /etc/firewalld/services/nomachine.xml

nomachine

NoMachine

tcp” port=”4000″/>

EOF

Configure firewalld

sudo firewall-cmd –permanent –zone=trusted –add-service=nomachine

sudo firewall-cmd –permanent –zone=home –add-service=nomachine

sudo firewall-cmd –permanent –zone=internal –add-service=nomachine

sudo firewall-cmd –permanent –zone=work –add-service=nomachine

sudo firewall-cmd –reload

Change to console boot (disable GUI boot). This is so the NoMachine X server is used, which will properly resize the remote display as the client window is resized.

sudo systemctl set-default multi-user.target

Configure pulseaudio to work with PipeWire (https://kb.nomachine.com/AR07T01168)

sudo dnf install pulseaudio –allowerasing

sudo dnf install pulseaudio-utils

sudo /usr/NX/scripts/setup/nxnode –audiosetup

Configure audio (https://forum.nomachine.com/topic/centos-nomachine-server-no-sound)

sudo /usr/NX/bin/nxnode –audiosetup /etc/pulse

sudo /etc/NX/nxserver –restart

Reboot

This topic was spun off from another post about audio (on Alma Linux) by the admins. Are you still having problems with getting audio to work?

For some tips on how to set up NoMachine with Pipewire, take a look at the following articles:
