This used to be disabled by default on CentOS only. Turn off sound forwarding to see if that's the case. If you want to disable this behaviour, either edit /etc/xpra/xpra/conf, or to do it for a single user: echo speaker=no >> ~/.xpra/xpra.conf
The next question that usually comes is to ask why we send sound data when no sound is being played through the virtual sound card (ie: not an application that uses sound), and the answer is that at the software level, we just can't tell the difference so we have to send it all the time. (also because we can't start playing sound quickly enough to start it on demand, at least not all platforms) Just for completeness: another possibility is that the application you forward does repaint the screen even when nothing changes, some badly written applications do that - and if you use a non-video encoding, this would cause a fairly constant bandwidth usage. Similarly, some browsers will repaint pretty much the whole page as soon as you hover over a link anywhere.. In this case, you can minimize the window to confirm (minimized windows do not cause any traffic) You can also visualize how many pixels are being received per second on the "Graph" pane of the "Session Info" dialog.
