    Hi all, I’m new to NoMachine with Pi.

    I am running in to a problem running pacmd when logged in remotely with NoMachine using a Pi 4 Buster.  When I login via a connected console, there is no issue running pacmd.

    To get the standard LXDE-PI desktop to come up when logging in via NoMachine I had to add the line:

    DefaultDesktopCommand “/usr/bin/startlxde-pi”

    To /usr/NX/etc/node.cfg or else I got a generic LXDE desktop.   When I do this and login with NoMachine, all seems ok until I try to use any of the PulseAudio cli commands.   They all fail as follows:

    pi@PI-002:~ $ pacmd list-sinks
    No PulseAudio daemon running, or not running as session daemon.

    From reading online, this seems to be a problem with how X11 has been initialized when NoMachine logged in – but noone seems to offer any ideas on how to solve this issue.   I suspect this is simple but I can’t seem to “get” it.

    I am running the following hardware/software versions:

    Pi 4, 4GB (server), MacOS BigSur 11.1 (client)
    NoMachine:   Version 7.0.211 (arm7) — Server, Version 7.0.211 (OSX) — Client
    Raspian:  Buster (latest updates)

    Thanks for any help!


    does it give some error when try to manually start PA daemon.

    please try and give output or error message if it gives any:
    pulseaudio -D
