advertisements with sound, run rather smooth, but longer videos on youtube experience a "stuck image" effect that only goes away when moving the mouse over the area where the video plays (this helps for a few seconds, then you have to repeat the procedure), also, the sound starts to get choppy. BUT: This *might* be due to something weird in my LAN config or due to the client options I chose. It sure needs further testing and verification before it can be considered a bug.
Have you tried disabling (UNchecking) "Use SSH port forwarding to tunnel sound system connections through firewalls"?
I have found that all versions of Windows x2goclient after 3.01-13, including the latest 3.99.1.0 (preview2), have a problem with tunneling sound through firewalls. It will intermittently lock up. Sometimes it works fine for a while, but eventually the sound always locks up. Disabling tunneling fixes that issue for me.
