Hi,
This is not the problem created directly by NoMachine. On the contrary, PulseAudio needs client.conf file to work properly. Use this template to recreate it https://github.com/pulseaudio/pulseaudio/blob/master/src/pulse/client.conf.in
. Make sure that it has proper permission, owner and group.
Replace @PA_BINARY@ with path to PulseAudio Daemon, possible path is /usr/bin/pulseaudio and set autospawn = no
(simply paste it above ; autospawn = yes
) . Then reboot the machine.
If the problem still exists, please send us output of command pacmd list
.
Thanks,
mkub
