This really gives very little information to go on. Please ensure you
provide various logs etc. to give people hints.

Hi Col,
I am attaching the pulseaudio usb mic delay log.
When I am running gst-launch-0.10 ! pulsesrc ! pulsesink on pandaboard
getting around 2-3 sec. on the fly audio delay.
Please suggest how to resolve this problem.
