Comment 18 for bug 329896

 "Make discoverable network sound devices available locally" is wrong conceptually.

If one wants redirect audio, it's right to use CPU power of other machine, in other words the instance of Pulseaudio available through network. In this way, local Pulseaudio won't be used.
Turning the option on, local pulseaudio try to elaborate remote audio flow, with all the obvious delays.

Without this option all is OK :-)
