You can do this by running 'pamon' (from the pulseaudio-utils package) and assigning the stream you create to some sink. I just did it both by 'folding back' onto the same output device and by assigning to a new device. In both cases latency was not apparent -- when I folded back it sounded just like I increased the gain of the input stream. -- Paul W.
