Hi Tarun, Audio stability problem may be caused by varies conditions. Modifying jitter buffer setting may be needed if you are in a rather 'extreme' network environment. Or increase sound device latency/buffer to achieve stability on CPU load instability. In some cases, sound device drift may cause echo canceler to fail and even cause a noise. So it is necessary to identify the source of instability. So as usual, here may be a good starting point to identify (and solve) audio problems: http://trac.pjsip.org/repos/wiki/sound-problems.
