Yes, many things are different from VNC and x2go is one of them. It's not really a constructive comparison. VNC does not tunnel audio. It's simply not part of the protocol. For Guacamole to be able to provide audio when VNC is being used as the backend remote desktop protocol, Guacamole must connect separately to PulseAudio over the network. This means PulseAudio needs to be configured to (1) accept network connections and (2) send audio over the sink associated with those connections. There are other remote desktop protocols and servers (Windows RDP, for example) which do support audio natively and don't require a separate backend audio connection. That is not relevant to VNC. - Mike
