I try to setup a remote desktop using x2go with a headless Linux VM as a server (Centos 8 Stream) and Linux desktop (Fedora 35) as a client.

I have successfully set up generic desktop sharing and now fighting with sound forwarding.

I have ticked 'Enable sound support' and chose 'Pulseaudio' at X2Go client (native X2Go v.4.1.2.2 QT client). 

I've configured the PulseAudio natie tcp module on both sides.

However, I see only 'Dummy' sound device at remote end, and no sound at the client side.

Can anyone help with suggestions, how to troubleshoot this setup?
