NoMachine 8.10.1 Pipewire – no sound from server without physical sound card

[HonestCoder]

Hello.
I have VPS on CentOs 8 Stream, and use it from remote Fedora 39. Both use pipewire. CentOs does not have physical sound card.
I load dummy sound by add /etc/modules-load.d/vsound.cfg with sbnd-dummy in it. Now I have sound devices on CentOs

I setup pipewire-utils at Centos, and have pw-cli here (NoMachine need it to detect pipewire). I set UDPPort 4800-4999 in server.cfg on CentOs. I open incoming connection to these ports on the side of CentOs (was it necessary ? What ports may be open for incoming connections on client and server ?)

Anyway, I do not listen any sound from server on my client Fedora. Also I try to intercept 4800-4999 UDP port range at CentOs. It is no any packets on it`s, then I try to play any sound at CentOs server.

What is wrong ?

Try to replace PipeWire on Puilseaudio, as in FAQ of NoMachine.
For CentOs 8 by commands:
dnf remove pipewire
dnf install alsa-plugins-pulseaudio
systemctl –global enable pulseaudio.service
/usr/NX/scripts/setup/nxnode –audiosetup

Do not help.
No sound on client
No UDP packages (excl main port) from server, then try to check sound play on server.

Please help.
