Should I disable it and try again? Rather not. Let's try something else. sudo dtruss -fn pulseaudio Then, in another shell, execute /Applications/x2goclient.app/Contents/exe/pulseaudio --version If that doesn't work (i.e., dtrace doesn't see the newly spawned process), maybe you'll need to give /Applications/x2goclient.app/Contents/exe/pulseaudio as the argument to -n instead.
