Fedora 39 pipewire – no audio

[CRCinAU]

Hi all,

Started a clean install of Fedora 39 to use as a NoMachine host.

When trying to get the audio working, I don’t see anything other than Dummy Output from the Gnome settings…

# pactl info
Server String: /run/user/1000/pulse/native
Library Protocol Version: 35
Server Protocol Version: 35
Is Local: yes
Client Index: 55
Tile Size: 65472
User Name: netwiz
Host Name: fedora-rdp
Server Name: PulseAudio (on PipeWire 0.3.84)

[/code]

I checked /usr/NX/etc/node.cfg and the following is set:
[code]
AudioInterface pipewire

What else should be checked?

Hi,

Are you able to hear sound from your machine outside NoMachine session? I’m not sure if it’s possible if you only have auto_null. Your built-in device should be set as the default sink, or some other physical device, i.e. headphones or external speakers. When NoMachine makes a connection between two machines, it connects to the default sink and captures its output data. This means that even if NoMachine is able to connect to auto_null (Dummy Output), if auto_null doesn’t receive any data, you don’t hear anything on the client side.

If your Fedora is a virtual machine, you should probably connect it to the speaker of the physical machine and enable audio in virtual box settings (or any software you’re using for virtualization) and then test the connection via NoMachine.

Regards,

Kuba

I came back to this after finding out that pipewire is not supported for Virtual Desktops….

As such, I reverted to pulseaudio. The nxnode --audiosetup didn’t work as there was no /etc/pulse/client.conf.

I copied that in from somewhere in /usr, and ran nxnode --audiosetup again, and after that point, all works.
