As the playback has almost no latency, i suspect the latency coming from the
capture routine:
gst-launch-0.10 souphttpsrc
location=http://localhost:4714/listen/source/alsa_input.pci-0000_00_1b.0.analog-stereo
！ decodebin ! pulsesink
(This test command doesnot work for me, there's error)
And in such scenario, the data path is like:

capture data-->PA
Source-->http-protocol-->bin-->buffer?-->native-protocol-->PA-->Sink

currently i'm blocked by above test command, it doesnot work for me.

thanks
